**Oliver Dimon Kellogg** (10 July 1878 – 27 August 1932) was an American mathematician.^{[1]}

His father, Day Otis Kellogg, was a professor of literature at the University of Kansas and editor of the American edition of the *Encyclopædia Britannica*. In 1895 Oliver Kellogg began his undergraduate study at Princeton University, where he earned his master's degree in 1900. With a John S. Kennedy stipend he first studied at the Humboldt University of Berlin and then in 1901/1902 at Georg-August-Universität Göttingen. At Göttingen in 1902 he earned his PhD with a thesis *Zur Theorie der Integralgleichungen und des Dirichlet'schen Prinzips* under the direction of David Hilbert. After completing his thesis, Kellogg became an instructor at Princeton and from 1905 at the University of Missouri, where he became a professor in 1910. In World War I he was a scientific advisor at the Coast Guard Academy in New London, Connecticut, where he worked on submarine detection. Kellogg became a lecturer at Harvard University in 1919, an associate professor in 1920, and a professor in 1927. He died of a heart attack while climbing Doubletop Mountain near Greenville, Maine.^{[2]}^{[3]} Kellogg was married and had a daughter.

Kellogg is known for his work on potential theory, which was the subject of his dissertation and also his famous 1929 textbook *Foundations of Potential Theory*.^{[4]} In 1922 with George David Birkhoff he generalized the Brouwer fixed point theorem to the theorem of Birkhoff–Kellogg.

Among his doctoral students was Arthur Copeland.
