Andrew Walter Reid (born March 19, 1958) is an American professional football coach who is the head coach of the Kansas City Chiefs of the National Football League (NFL). Reid was previously head coach of the Philadelphia Eagles from 1999 to 2012. From 2001 to 2012, he was also the Eagles' executive vice president of football operations. He is the only NFL coach to win 100 games and appear in four consecutive conference championships with two different franchises.

Reid began his professional coaching career with the Green Bay Packers, where he served as an offensive assistant from 1992 to 1998 and was a member of the team that won Super Bowl XXXI. He held his first head coaching position with the Eagles in 1999, who became perennial postseason contenders under his leadership. Reid led the Eagles to nine playoff runs, six division titles, five NFC Championship Games (including four consecutive from 2001 to 2004), and an appearance in Super Bowl XXXIX. Despite his success, Reid was unable to win a Super Bowl title and he was fired from Philadelphia after the 2012 season.

Hired as the head coach of the Chiefs in 2013, Reid helped revitalize the struggling franchise into the league's best. In 11 seasons with Kansas City, he has led the Chiefs to 10 postseason appearances, eight consecutive division titles, six consecutive AFC Championship Games, four Super Bowl appearances, and three Super Bowl titles. Reid also won the Chiefs' first playoff game since 1993 in the 2015 season, clinched their first consecutive division titles between 2016 and 2017, and won their first Super Bowl in 50 years in Super Bowl LIV.
