The Western Hemisphere is a geographical term for the half of Earth which lies west of the prime meridian (which crosses Greenwich, London, United Kingdom) and east of the antimeridian. The other half is called the Eastern Hemisphere.
The Western Hemisphere consists of the Americas, the western portions of Eurasia and Africa, the extreme eastern tip of Siberia (Russia), numerous territories in Oceania, and a portion of Antarctica, while excluding some of the Aleutian Islands to the southwest of the Alaskan mainland.
In an attempt to define the Western Hemisphere as the parts of the world which are not part of the Old World, there also exist projections which use the 20th meridian west and the diametrically opposed 160th meridian east to define the hemisphere. This projection excludes the European and African mainlands and a small portion of northeast Greenland, but includes more of eastern Russia and Oceania.
The center of the Western Hemisphere is located in the Pacific Ocean at the intersection of the 90th meridian west and the Equator, among the Galápagos Islands. The nearest land is Genovesa Island at .

Below is a list of the sovereign states which are in both the Western and Eastern Hemispheres along the 180th meridian, in order from north to south. With the exception of the United States (Wake Island), all of them are located on just one side of the International Date Line, which is curved around them.
The following countries and territories lie outside the Americas yet are entirely/mostly or partially within the Western Hemisphere:
The Assistant Secretary of State for Western Hemisphere Affairs is the head of the Bureau of Western Hemisphere Affairs within the United States Department of State, the foreign affairs department of the United States federal government. The Assistant Secretary of State guides operation of the U.S. diplomatic establishment in the countries of the Western Hemisphere and advises the Secretary of State and the Under Secretary for Political Affairs.
The Department of State created the position of Assistant Secretary of State for American Republic Affairs during the general reorganization of December 20, 1944, after Congress had authorized an increase in the number of Assistant Secretaries of State from four to six. This reorganization was the first to assign substantive designations to specific Assistant Secretary positions. The position was temporarily discontinued between June 1947 and June 1949, when American Republic Affairs were handled by an Assistant Secretary for Political Affairs.The Department re-established the position in June 1949 after the Commission on Organization of the Executive Branch of Government recommended that certain offices be upgraded to bureau level and after Congress increased the number of Assistant Secretaries of State from six to ten. On October 3, 1949, the Department by administrative action changed the incumbent's designation to Assistant Secretary for Inter-American Affairs. The Department of State had first established a Division of Latin American Affairs in 1909.Bureau of Western Hemisphere Affairs
In the United States government, the Bureau of Western Hemisphere Affairs (WHA) is a part of the U.S. Department of State, charged with implementing U.S. foreign policy and promoting U.S. interests in the Western Hemisphere, as well as advising the Under Secretary of State for Political Affairs. It is headed by the Assistant Secretary of State for Western Hemisphere Affairs, who is currently Acting Assistant Secretary Francisco Palmieri.Common black hawk
The common black hawk (Buteogallus anthracinus) is a bird of prey in the family Accipitridae, which also includes the eagles, hawks, and Old World vultures. It formerly included the Cuban black-hawk (Buteogallus gundlachii) as a subspecies. The mangrove black hawk, traditionally considered a distinct species, is now generally considered a subspecies, B. a. subtilis, of the common black-hawk.Cordillera
A cordillera is an extensive chain of mountains or mountain ranges. The term is a borrowing from Spanish, in which it has the same meaning. The Spanish word originates from cordilla, a diminutive of "cuerda" or "rope". It is most commonly used in the field of physical geography.The term is particularly applied to the various ranges of the Andes of South America, and less frequently to other mountain ranges in the "ridge" that rims the Pacific Ocean. In Colombia and Venezuela the cordilleras are named according to their position: Cordillera Occidental, Central, and Oriental. Various local names identify the cordilleras in Ecuador, Peru, Bolivia, Chile, and Argentina.
Mountain ranges of this type have a complex structure, usually the result of folding and faulting accompanied by volcanic activity. In South America the ranges include numerous volcanic peaks. The Andes cordillera has Ojos del Salado, the highest active volcano in the world and second highest point in the Western Hemisphere. (Though not itself a volcano, Argentina's Mt. Aconcagua, at 6,960 metres (22,834 feet) high, is the highest point in the Western Hemisphere.) A number of the volcanoes have been active in historical times. Aside from the volcanic peaks, the crests include many narrow ridges, some of which reach into the zone of permanent snow. Between the ranges there are numerous inhabited valleys, basins, and low plateaux with a wide range of elevations.EBird
eBird is an online database of bird observations providing scientists, researchers and amateur naturalists with real-time data about bird distribution and abundance. Originally restricted to sightings from the Western Hemisphere, the project expanded to include New Zealand in 2008, and again expanded to cover the whole world in June 2010. eBird has been described as an ambitious example of enlisting amateurs to gather data on biodiversity for use in science.eBird is an example of crowdsourcing, and has been hailed as an example of democratizing science, treating citizens as scientists, allowing the public to access and use their own data and the collective data generated by others.Eastern Hemisphere
The Eastern Hemisphere is a geographical term for the half of Earth which is east of the prime meridian (which crosses Greenwich, London, UK) and west of the antimeridian (which crosses the Pacific Ocean and relatively little land from pole to pole). It is also used to refer to Afro-Eurasia (Africa and Eurasia) and Australia, in contrast with the Western Hemisphere, which includes mainly North and South America. The Eastern Hemisphere may also be called the "Oriental Hemisphere". In addition, it may be used in a cultural or geopolitical sense as a synonym for the "Old World".FIBA AmeriCup
The FIBA AmeriCup (previously known as the FIBA Americas Championship) is the name commonly used to refer to the American Basketball Championship that takes place every two years between national teams of the Western Hemisphere continents. Through the 2015 edition, the Americas Championship was also a qualifying tournament for the FIBA World Cup and the Summer Olympic Games. Beginning in 2017, the championship, along with all other FIBA continental championships for men, is played once every four years, and the continental championships are no longer a part of the qualifying process for either the World Cup or Olympics.Since FIBA organized the entire Western Hemisphere west of the Atlantic Ocean under one zone, countries from Northern America, Central America, the Caribbean and South America compete in this tournament.
The United States is the most successful team in this tournament, having won it seven times. Argentinean Luis Scola, is both the all-time leading scorer in tournament history, and the player who has won the most tournament MVPs, with four.Johnson Doctrine
The Johnson Doctrine, enunciated by U.S. President Lyndon B. Johnson after the United States' intervention in the Dominican Republic in 1965, declared that domestic revolution in the Western Hemisphere would no longer be a local matter when "the object is the establishment of a Communist dictatorship". It is an extension of the Eisenhower and Kennedy Doctrines.List of mosques in the Americas

The New World is one of the names used for the majority of Earth's Western Hemisphere, specifically the Americas (including nearby islands such as those of the Caribbean and Bermuda), and Oceania.
The term originated in the early 16th century after Europeans made landfall in what would later be called the Americas in the age of discovery, expanding the geographical horizon of classical geographers, who had thought of the world as consisting of Africa, Europe, and Asia, collectively now referred to as the Old World (a.k.a. Afro-Eurasia).
The phrase gained prominence after the publication of a pamphlet titled Mundus Novus attributed to Italian explorer Amerigo Vespucci.The Americas were also referred to as the "fourth part of the world".Red phalarope
The red phalarope (called grey phalarope in Europe), Phalaropus fulicarius, is a small wader. This phalarope breeds in the Arctic regions of North America and Eurasia. It is migratory, and, unusually for a wader, migrating mainly on oceanic routes and wintering at sea on tropical oceans.Roosevelt Corollary
The Roosevelt Corollary was an addition to the Monroe Doctrine articulated by President Theodore Roosevelt in his State of the Union address in 1904 after the Venezuela Crisis of 1902–1903. The corollary states that the United States will intervene in conflicts between the European countries and Latin American countries to enforce legitimate claims of the European powers, rather than having the Europeans press their claims directly.
Roosevelt tied his policy to the Monroe Doctrine, and it was also consistent with his foreign policy included in his Big Stick Diplomacy. Roosevelt stated that in keeping with the Monroe Doctrine, the United States was justified in exercising "international police power" to put an end to chronic unrest or wrongdoing in the Western Hemisphere. While the Monroe Doctrine had sought to prevent European intervention, the Roosevelt Corollary was used to justify US intervention throughout the hemisphere. In 1934, President Franklin D. Roosevelt renounced interventionism and established his Good Neighbor policy for the Western Hemisphere.Semipalmated sandpiper
The semipalmated sandpiper (Calidris pusilla) is a very small shorebird. The genus name is from Ancient Greek kalidris or skalidris, a term used by Aristotle for some grey-coloured waterside birds. The specific pusilla is Latin for "very small".It is sometimes separated with other "stints" in Erolia, but, although these apparently form a monophyletic group, the present species' old genus Ereunetes had been proposed before Erolia.Spanish language in the Americas
The different varieties of the Spanish language spoken in the Americas are distinct from Peninsular Spanish and Spanish spoken elsewhere, such as in Africa and Asia. Linguistically, this grouping is somewhat arbitrary, akin to having a term for "overseas English" encompassing variants spoken in the United States, Canada, Australia, India, New Zealand and Ireland, but not the Island of Britain. There is great diversity among the various Latin American vernaculars, and there are no traits shared by all of them which is not also in existence in one or more of the variants of Spanish used in Spain. A Latin American "standard" does, however, vary from the Castilian "standard" register used in television and notably the dubbing industry.
Of the more than 469 million people who speak Spanish as their native language, more than 418 million are in Latin America and the United States.There are numerous regional particularities and idiomatic expressions within Spanish. In Latin American Spanish, loanwords directly from English are relatively more frequent, and often foreign spellings are left intact. One notable trend is the higher abundance of loan words taken from English in Latin America as well as words derived from English. The Latin American Spanish word for "computer" is computadora, whereas the word used in Spain is ordenador, and each word sounds foreign in the region where it is not used. Some differences are due to Iberian Spanish having a stronger French influence than Latin America, where, for geopolitical reasons, the United States influence has been predominant throughout the twentieth century.Stilt house
Stilt houses are houses raised on piles over the surface of the soil or a body of water. Stilt houses are built primarily as a protection against flooding, and they also keep out vermin. The shady space under the house can be used for work or storage.United States Senate Foreign Relations Subcommittee on Western Hemisphere and Global Narcotics Affairs

The Western Hemisphere Institute for Security Cooperation (WHINSEC) is a United States Department of Defense Institute located at Fort Benning near Columbus, Georgia, created in the 2001 National Defense Authorization Act.Western Hemisphere Region (World Association of Girl Guides and Girl Scouts)
The WAGGGS-Western Hemisphere Region is the divisional office of the World Association of Girl Guides and Girl Scouts, which services Guiding and Scouting in North and South America.
This region is the counterpart of the Interamerican Region of the World Organization of the Scout Movement (WOSM).
