Robert Merrell Gage (December 26, 1892 – October 30, 1981) was an American sculptor, frequently credited or referred to as Merrell Gage.

Gage was born in Topeka, Kansas and studied in the Topeka public schools and at Washburn University. He worked on ranches in the Midwest before settling on an art career.[1] He studied art in New York and France and worked in the studio of Gutzon Borglum as an assistant. In 1916, he set up a sculpture studio in a barn behind his house in Topeka. His first public commission was for a statue of Abraham Lincoln that is now on the grounds of the Kansas State Capitol.

He married Marian Gage, a painter, shortly after World War I when he was in the medical corps and lived in Kansas City.[2] He began teaching sculpture at Washburn and at the Kansas City Art Institute.[3] They moved to Los Angeles from New York in 1924 and built a studio in their home in the Santa Monica Canyon.[2] He was appointed professor of sculpture at the University of Southern California and rose to the head of the department. Gage’s mother and sister lived in La Jolla, San Diego, California.
