Augustus Franklin Allen (December 13, 1813 – January 20, 1875) was elected as a member of the United States Congress from New York's 33rd congressional district (Chautauqua and Cattaraugus Counties) in 1874.

He was educated locally and began working as a store clerk at age 17 in order to support his family after his father's death.

He resided in Ellicott, was successful in business, and later became a partner in a lumber yard, woolen mill, railroads and other ventures.

During the Civil War he was appointed to organize, equip, and train the 112th New York Infantry and commissioned as a colonel.

He led the regiment for several months until being succeeded by Jeremiah C. Drake, who commanded until dying of wounds received at the Battle of Cold Harbor.
