The 1909 College Football All-America team is composed of college football players who were selected as All-Americans for the 1909 college football season. The only selector for the 1909 season who has been recognized as "official" by the National Collegiate Athletic Association (NCAA) is Walter Camp. Many other sports writers and newspapers also selected All-America teams in 1909. The United Press and The Atlanta Constitution both published their own "consensus" All-America teams based on their aggregating the first-team picks of a number of selectors.

David Way Allerdice was an American football player and coach. He played college football as the University of Michigan as a halfback from 1907 to 1909. Allerdice served as the head football coach at Butler University in 1911 and the University of Texas at Austin from 1911 to 1915. He left Butler after the team's first game in early October to move to Texas, succeeding his former Michigan teammate Billy Wasmund, who had died from a fall.
