Andrew Walter Reid (born March 19, 1958) is an American professional football coach who is the head coach for the Kansas City Chiefs of the National Football League (NFL). Reid was previously the 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. Reid is the only NFL coach to win 100 games with two different franchises and also the only coach to appear in four consecutive conference championships with two different franchises. He is considered one of the greatest NFL coaches of all time.

Reid began his professional coaching career with the Green Bay Packers, serving 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. Reid was fired after the 2012 season as the Eagles had missed the postseason for a second straight year.

Hired as the head coach of the Chiefs in 2013, Reid helped revitalize the struggling franchise into the league's best. The Chiefs won 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. In 12 seasons with Kansas City, Reid has led the Chiefs to 11 postseason appearances, nine consecutive division titles, seven consecutive AFC Championship Games, five Super Bowl appearances (including three consecutive from Super Bowl LVII to LIX), and three Super Bowl titles.
