The 2002–03 season was Arsenal Football Club's 11th season in the Premier League and their 77th consecutive season in the top flight of English football. The club retained the FA Cup, a feat last achieved by Tottenham Hotspur in 1982, but finished runners-up to Manchester United in the Premier League. In the UEFA Champions League, defeat to Valencia in the second group stage meant Arsenal exited the competition at the same round for the second successive year.
