William Mack Brown (born August 27, 1951) is an American college football coach.

He is credited with revitalizing the North Carolina and Texas football programs.

Brown coached the Longhorns to victory against the top-ranked USC Trojans at the 2006 Rose Bowl game to cap off an undefeated season, win a second consecutive Rose Bowl, and the national championship in what has been considered one of the greatest games in college football history. Brown's Longhorns defeated Red River Showdown conference rival Oklahoma in 1998, 1999, 2005, 2006, 2008, 2009, and 2013.

In 2006, he was awarded the Paul "Bear" Bryant Award for "Coach of the Year". Brown achieved his 200th career win during the 2008 season, making him the first Texas coach to reach that mark. He resigned after the 2013 Alamo Bowl.Since returning to Chapel Hill, Brown has become Carolina's all-time winningest coach, passing Dick Crum for most wins in program history.
