The 2004–05 FA Premier League (known as the Barclays Premiership for sponsorship reasons) began on 14 August 2004 and ended on 15 May 2005.

Arsenal were the defending champions after going unbeaten the previous season.

Chelsea won the title with a record 95 points, securing the title with a 2-0 win at The Reebok Stadium against Bolton Wanderers.

Managed by José Mourinho during his first season at the club, Chelsea won the Premier League title (their first league title in 50 years).

Mourinho's season was also notable for the number of records set during the season: Fewest goals against in a Premier League season (15), most clean sheets kept in a season (25), most wins in a season (29), most consecutive away wins (9) and the most points in a season (95).
