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.
