The 1911 St. Bonaventure Brown and White football team represented St. Bonaventure University during the 1911 college football season. Under first-year head coach and captain Daniel Pickett, the St. Bonaventure eleven compiled a 2–2 record, and were outscored by their opponents 80 to 11. They posted two shutouts, against Bradford, and Lebanon Valley, while themselves being shut out twice by two college football powerhouses, undefeated co-national champion Penn State (NCF), and a Notre Dame team that went undefeated, and outscored their opponents 222 to 9. Nicknames for the football team included the Brown and White, as that was their school colors, and the Alleganians, given St. Bonaventure's proximity to Allegany, New York.

The 1911 college football season was the last one before major reforms were made to the American game in 1912. In 1911, touchdowns were worth five points, the field was 110 yards in length, and a team had three downs within which to advance the ball ten yards. The United States Naval Academy (Navy) finished with a record of 6 wins and 3 ties (6–0–3). Two of the ties were 0–0 games with the other major unbeaten teams, Penn State (8–0–1) and Princeton (8–0–2). Other teams that finished the season unbeaten were Minnesota (6–0–1) and Florida (5–0–1). The Helms Athletic Foundation, founded in 1936, declared retroactively that Princeton had been the best team of 1911
