The Premier League is an English professional league for association football clubs. At the top of the English football league system, it is the country's primary football competition. Contested by 20 clubs, it operates on a system of promotion and relegation with the Football League. The Premier League is a corporation in which the 20 member clubs act as shareholders. Seasons run from August to May, with teams playing 38 matches each, totalling 380 matches in the season. Most games are played on Saturdays and Sundays, with a few games played during weekday evenings. It was known as the Premiership from 1993 to 2007. It is currently sponsored by Barclays Bank and therefore officially known as the Barclays Premier League.

The competition formed as the FA Premier League on 20 February 1992 following the decision of clubs in the Football League First Division to break away from The Football League, which was originally founded in 1888, and take advantage of a lucrative television rights deal. This was worth £2 billion in 2008–09. The Premier League is the most-watched football league in the world, broadcast in 212 territories to an audience of 643 million viewers. In the 2010–11 season the average Premier League match attendance was 35,363, the second highest of any professional football league behind the German Bundesliga, and stadium occupancy was 92.2% full. The Premier League ranked first in the Union of European Football Associations (UEFA) coefficients of leagues based on performances in European competitions over the last five years, ahead of the Spanish La Liga and German Bundesliga.
