The 1909 Yale Bulldogs football team was an American football team that represented Yale University as an independent during the 1909 college football season. The team finished with a 10–0 record, shut out every opponent, and outscored them by a total of 209 to 0.[1] Howard Jones was the team's head coach, and Ted Coy was the team captain.
There was no contemporaneous system in 1909 for determining a national champion. However, Yale was retroactively named as the national champion by the Billingsley Report, Helms Athletic Foundation, Houlgate System, National Championship Foundation, and Parke H. Davis.[2]
Six Yale players were selected as consensus first-team players on the 1909 All-America team. The team's consensus All-Americans were: fullback Ted Coy; halfback Stephen Philbin; end John Kilpatrick; center Carroll Cooney; guard Hamlin Andrus; and tackle Henry Hobbs.[3]
