The North Pacific Fur Seal Convention of 1911, formally known as the Convention between the United States and Other Powers Providing for the Preservation and Protection of Fur Seals, was an international treaty signed on July 7, 1911, designed to manage the commercial harvest of fur-bearing mammals (such as Northern fur seals and sea otters) in the Pribilof Islands of the Bering Sea. The treaty, signed by the United States, the United Kingdom of Great Britain and Ireland, the Empire of Japan, and the Russian Empire, outlawed open-water seal hunting and acknowledged the United States' jurisdiction in managing the on-shore hunting of seals for commercial purposes. It was the first international treaty to address wildlife preservation issues.
The two most significant terms of the treaty were the banning of pelagic seal hunting and the granting of jurisdiction to the United States in managing on-shore hunts. In exchange for granting jurisdiction to the United States, the other signatories to the treaty were guaranteed payments and/or minimum takes of seal furs while the treaty remained in effect, subject to certain conditions.
The treaty also provided an exemption to aboriginal tribes which hunted seals using traditional methods and for non-commercial purposes including food and shelter. Aboriginal tribes specifically mentioned in the treaty include the Aleut and Aino (Ainu) peoples.<, ref name="Text"/>
The treaty was co-authored by environmentalist Henry Wood Elliott and United States Secretary of State John Hay in 1905, although the treaty was not ratified for another six years.  The treaty was signed at Washington, D.C. on July 7, 1911, with ratifications by each signatory on the following dates:
Ratifications were then exchanged at Washington on December 12, 1911, and the treaty was proclaimed two days later on December 14.
Following ratification, the United States Congress enacted an immediate five-year moratorium on hunting, to allow for recovery of the decimated herds. The treaty remained in effect until hostilities erupted among the signatories in World War II. However, the treaty set precedent for future national and international laws and treaties, including the Fur Seal Act of 1966 and the Marine Mammal Protection Act of 1972. On the 100th anniversary of the treaty in 2011, the Pribilof Fur Seal Monument was erected.
