Elvis Kool Dumervil (born January 19, 1984) is an American football defensive end for the Denver Broncos of the National Football League (NFL). He was drafted by the Broncos in the 2006 NFL Draft in the 4th round. He played college football at Louisville.

Dumervil's parents were Haitian immigrants to Miami's Little Haiti neighborhood. Separated when Dumervil was 3, they raised a total of 10 children. Rated among the top 25 defensive ends by most publications, Dumervil had a Miami Jackson High School record 78 career sacks.

His college career began slowly as a modest contributor during his first two seasons at the University of Louisville; he tallied just 28 tackles and two sacks. John L. Smith's staff had planned on redshirting him during the 2002 season, but injuries to other players and a lackluster performance by the defensive line forced him into the rotation.

He emerged during the 2004 season as a junior, recording 10 sacks and 11 tackles for a loss. His 2005 season was one of the best for a defensive end in both NCAA and school history, when he broke the NCAA single-game sack record (6) in a game against the rival Kentucky Wildcats, and broke the NCAA record for forced fumbles. His sack total also broke the Big East record set by Dwight Freeney, who was a player that Elvis desired to emulate. He won several awards for the 2005 season, including the Bronko Nagurski Trophy, the Ted Hendricks Award, and Big East player of the year, and was recognized as a consensus first-team All-American.
