Elvis Kool Dumervil (born January 19, 1984) is an American former professional football defensive end and linebacker who played in the National Football League (NFL) for 12 seasons. He played college football for the Louisville Cardinals, winning the Bronko Nagurski Trophy and Ted Hendricks Award as a senior, and was selected by the Denver Broncos in the fourth round of the 2006 NFL draft.

During his seven seasons with the Broncos, Dumervil was the NFL sacks leader in 2009. He was also named to two Pro Bowls and one first-team All-Pro. Dumervil spent his next four seasons with the Baltimore Ravens, where he extended his Pro Bowl selections to five and his first-team All-Pros to two, as well as setting the franchise record for single-season sacks. In his final season, he was a member of the San Francisco 49ers.

Dumervil was born in Miami, Florida. His parents were Haitian immigrants to Miami's Little Haiti neighborhood. Dumervil was named after Elvis Presley, of whom his father was a fan. Separated when Dumervil was three years old, they raised a total of 10 children. His half-brother Curry Burns (born 1981) is a former football safety.

Dumervil attended Miami Jackson High School, where he was a two-sport star in football and track. He played high school football for the Jackson Generals team. Rated among the top 25 defensive ends by most football recruiting publications, Dumervil had a Jackson High School record 78 career sacks.

Despite standing at 5 ft. 11 in., Dumervil was one of the most dominating defensive players in school history and put together one of the most impressive collegiate seasons in 2005. A native of Miami, Fla., Dumervil attended the University of Louisville, where he played for coach John L. Smith (2002) and Bobby Petrino's Louisville Cardinals football team from 2003 to 2005. As a freshman in 2002, Dumervil recorded six tackles and two tackles for loss, but he impressed the coaching staff with his quickness and his high energy. After John L. Smith left, Petrino took over, and Dumervil's career took off. In 2003, he tallied just 28 tackles and two sacks. The Cardinal coaching 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 showed glimpses of what was to come in 2004, when he tallied 52 tackles, 11.5 tackles for loss and a team-high 10 sacks in guiding the Cardinals to an 11–1 record and a win over Boise State in one of the most anticipated Liberty Bowls in history. 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 31–24 win 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 finished that season with a school record 20.5 sacks and 10 forced fumbles, which is still the best in NCAA history. 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 unanimous first-team All-American.

In the 2006 Gator Bowl, Virginia Tech quarterback Marcus Vick intentionally stomped on the back of Dumervil's leg after a whistle. While no penalty was called, the backlash from this play (in combination with a misdemeanor charge for driving with a suspended license) led to Vick's permanent dismissal from the Virginia Tech football team. Vick claimed that he had apologized to Dumervil after the game, while Dumervil disputed that claim and stated that he didn't receive any kind of apology from Vick.

In college, he was known for the "strip-sack" maneuver where he would sometimes strip the ball from ball carriers or quarterbacks.
