Abraham Lincoln Manley (December 22, 1885 – December 9, 1952) was an American Negro league baseball executive. Manley co-owned the Newark Eagles baseball franchise in the Negro leagues with his wife, Effa Manley, from 1935 to 1946.
Manley bought the Brooklyn Eagles and Newark Dodgers and merged them into the Newark Eagles in 1936. An active owner, Manley also served as vice president and treasurer of the Negro National League at one point and also managed the Eagles in 1936 and 1938.
He met his wife, Effa, at a New York Yankees game in 1935, and involved her in the operation of his club.
Manley was born in Hertford, North Carolina and died in Germantown, Pennsylvania.
He was among the 94 Negro league figures on the Baseball Hall of Fame ballot in 2006, but was not selected, although his wife became the first woman to be inducted into the Baseball Hall of Fame.
