is an English former professional footballer who played as a centre back or right back. He spent the majority of his career at Manchester United, where he won 13 trophies including five Premier League titles and two UEFA Champions Leagues.

Brown began his career with Manchester United by joining the club's academy at the age of 12 in 1992. After turning professional in 1996, he made his senior debut in 1998 and became a semi regular first team player during the 1998–99 season, when the club won the Treble. After a year-long hiatus due to injury, Brown became a regular fixture in the first team from 2000 onwards. Over the next eight years, he won numerous honours, including four more Premier League titles and another Champions League. Former Manchester United manager Sir Alex Ferguson has stated that Brown is \"without question the best natural defender this club has had for years\". After 15 years with Manchester United, Brown was allowed to leave for Sunderland, where he spent five years and helped them reach the 2014 League Cup final.

Brown earned his first England cap in 1999 and was selected to play at the 2002 World Cup. He played in the UEFA Euro 2008 qualifiers but England failed to progress to the final tournament. He scored his first international goal in 2008 against the Czech Republic. Brown announced his retirement from international football on 8 August 2010, just a day after being recalled to the England squad by Fabio Capello.
