Robert Garrison was an American sculptor (May 30, 1895–1945). He was born in Fort Dodge, Iowa.
Garrison studied at the Pennsylvania Academy of Fine Arts in Philadelphia and with Gutzon Borglum. He made his home in Denver, Colorado where he served on the faculty of the University of Denver and some of his work can be found.
His works include the Boston Avenue Methodist Church in Tulsa, Oklahoma, and stone reliefs on the Sixth Avenue side of Rockefeller Center in New York City. Additional works include architectural sculptures in the style of medieval grotesques at South High School, Denver and the figures of the four evangelists on the bell tower of the former St. Thomas Seminary, Denver. His two monumental molded concrete figures of athletes were integral to the University of Denver's Hilltop Stadium (1926), and were demolished along with the stadium in 1971.
