The 1921 University Farm football team represented the University Farm—now known as the
University of California, Davis—as an independent during the
1921 college football season. Although "University Farm" was the formal name for the school and team, in many newspaper articles from the time it was called "Davis Farm". The team had no nickname in 1921, with the "Aggie" term being introduced in 1922. Led by
Wilmer D. Elfrink in his first and only season as head coach, the team compiled a record of 3–4 and was outscored its opponents 131 to 78 for the season. The University Farm played home games in
Davis, California.
