Leslie Edwin "Les" Miles (born November 10, 1953) is an American college football coach and the current head coach of the Louisiana State University football team. Prior to holding that position, he was head coach at Oklahoma State. He was formerly an assistant at Oklahoma State as well as with the University of Michigan, the University of Colorado and the Dallas Cowboys. Miles has held the head coaching position at LSU since January 2005 and coached the Tigers to a win in the 2008 BCS National Championship Game against Ohio State, 38–24. On 26 August, 2011, his contract was extended to 2017.

Miles earned all-state honors in football at Elyria High School in Ohio as well as letters in baseball and wrestling. He attended the University of Michigan where he was a two-year letterman under Coach Bo Schembechler from 1974 to 75. In 1980, Miles returned to Michigan as an assistant coach to Schembechler. He left Michigan in 1982 to coach at the University of Colorado where fellow Michigan assistant Bill McCartney had just been named head coach. Coincidentally, one of his fellow assistants on the Colorado staff was another future LSU head coach, Gerry DiNardo, who coached at LSU from 1995–99.

He returned to Michigan in 1987 where he helped lead the team to eight consecutive winning seasons and bowl appearances, including four Rose Bowl appearances. After Gary Moeller's resignation, Miles left Michigan again to join former Colorado assistant Bob Simmons staff at Oklahoma State as offensive coordinator. A rift with the University of Michigan occurred near the time of Moeller's resignation, forcing him to seek employment elsewhere. During the 1998 through 2000 seasons he was the tight ends coach for the NFL's Dallas Cowboys.
