The English Football League (EFL) is a league of professional football clubs from England and Wales. Founded in 1888 as the Football League, the league is the oldest such competition in world football. It was the top-level football league in England from its foundation until 1992, when the top 22 clubs split from it to form the Premier League.

The EFL is divided into the Championship, League One and League Two, with 24 clubs in each division, 72 in total, with promotion and relegation between them; the top Championship clubs change places with the lowest-placed clubs in the Premier League, and the bottom clubs of League Two with the top clubs of the National League. Although primarily an English competition, clubs from Wales – currently Cardiff City, Swansea City and Newport County – also take part.

The Football League had a sponsor from the 1983–84 season, and thus was known by various names. For the 2016–17 season, the league rebranded itself as the English Football League (EFL).The English Football League also organises two knock-out cup competitions, the EFL Cup and the EFL Trophy. The operations centre of the Football League is in Preston, while its commercial office is in London.
