Derrick Lamar Henry Jr. (born January 4, 1994) is an American professional football running back for the Baltimore Ravens of the National Football League (NFL). Nicknamed "King Henry", he is known for his imposing style of play and larger build than the average running back. Noted for his success at every stage of his career, he is the only player to have rushed for at least 2,000 yards in a season at the high school, college and professional levels.

Born and raised in Yulee, Florida, Henry set the national high school football record for career rushing yards with the Yulee Hornets, breaking Ken Hall’s record that had stood for almost 60 years. He was a five star recruit according to ESPN. He played college football for the Alabama Crimson Tide, where during his junior season, he broke Herschel Walker's single-season college rushing yards record in the Southeastern Conference (SEC), won the 2015 Heisman Trophy, the Doak Walker Award, the Maxwell Award, and the Walter Camp Award, and was a key part of the 2015 Alabama Crimson Tide football team that won the 2016 College Football Playoff National Championship.

Henry was selected by the Tennessee Titans in the second round of the 2016 NFL draft, where he was a four-time Pro Bowl selection. A backup for most of his first two seasons in the league, Henry emerged as the Titans' feature back near the end of the 2018 season. He led the NFL in rushing yards for the 2019 season, as well as rushing touchdowns (tied with Green Bay Packers running back Aaron Jones). In 2020, Henry again led the league in rushing yards and touchdowns and became the eighth player in NFL history to rush for over 2,000 yards in a single season, and the second Tennessee Titan to do so, after Chris Johnson achieved it in 2009. Henry won the 2020 Associated Press NFL Offensive Player of the Year Award. After missing more than half of the 2021 season to injury, he made his third and fourth Pro Bowl appearances in the subsequent two seasons. After eight seasons with Tennessee, Henry signed with the Baltimore Ravens in 2024, where he set multiple franchise records in his first season with the team.
