Marlon Anthony Samuel (born November 14, 1955) is an American college football coach and former player. He served as head football coach at New Mexico State University (NMSU) from 1997 to 2004 and Southeast Missouri State University (SEMO) from 2005 to 2013, compiling a career college football record of 65 wins and 117 losses. Samuel had a 34–57 record at New Mexico State, which puts him at third all-time for wins in program history.
Samuel played four years at the University of Nebraska–Lincoln and was a member of Tom Osborne's first recruiting class. He was a two-year starter at defensive end, played in four bowl games and earned honorable mention All-Big Eight Conference honors as a senior.
From 1986 to 1996, Samuel coached the outside linebackers and rush ends at Nebraska, his alma mater, for head coach Tom Osborne. He mentored six first-team All-Americans and 12 future National Football League players, including first-round draft picks Broderick Thomas (1989), Mike Croel (1991), Trev Alberts (1994) and Grant Wistrom (1998). During Samuel's 11 seasons with the Cornhuskers, they were national champions in 1994 and 1995, captured seven Big Eight or Big 12 Conference championships, averaged 10 wins per year and played in 11 bowl games.
At New Mexico State from 1997 to 2004 as his contract was not renewed, Samuel compiled a 34–57 record. Their 6–5 record in 1999 was the best since 1992 and a 7–5 record in 2002 was their best record since 1970 until the 2023 season.
A native of Trinidad, Trinidad and Tobago, West Indies, Samuel moved to Jersey City, New Jersey, at the age of 10. He earned his B.S. degree in education from Nebraska in 1981.
