Michael Lionel Howell (born July 5, 1943) is an American former professional football player who was a defensive back in the National Football League (NFL) for the Cleveland Browns and Miami Dolphins. Howell played college football for the Grambling State Tigers and was selected by the Browns in the eighth round of the 1965 NFL draft.

A college quarterback, Howell converted to defensive back in the NFL. He felt he had no chance playing quarterback in the NFL due to his race. At the time African-Americans were stereotyped as not being able to successfully play the position. "I know I'm not going into the NFL as a black quarterback," is what Howell told his coach, the legendary Eddie Robinson. So, he changed to cornerback, winning a starting job in 1966, and moved to free safety in 1968. Howell did not miss a league game during his career in Cleveland, and intercepted 27 passes during his NFL career.

In 2012, the Cleveland Plain Dealer selected Howell as one of the 100 best players in Browns history.
