Lamar "Buddy" Allen (November 25, 1914 – May 16, 1989) was an American college football player and coach and baseball center fielder in the Negro leagues. He served as the head football coach at Arkansas Agricultural, Mechanical & Normal College (Arkansas AM&N)—now known as University of Arkansas at Pine Bluff—for four seasons, from to 1946 to 1949, compiling a record of 17–19–5.
Allen played as a back for Pine Bluff Merrill High School, a segregated black school in Arkansas, which won national championships in 1932, his freshman year, and 1933. His accomplishments were such that even the state's white newspapers, including the Arkansas Gazette took notice. He played baseball with the Birmingham Black Barons in 1940.
