The English Football League Championship, known simply as the Championship in England and for sponsorship purposes as Sky Bet Championship, is the highest division of the English Football League (EFL) and second-highest overall in the English football league system, after the Premier League, and is currently contested by 24 clubs.
Introduced for the 2004–05 season as the Football League Championship, the division is a rebrand of the former Football League First Division, which itself is a rebrand of the now-defunct Football League Second Division prior to the 1992 launch of the Premier League. The winning club of this division each season receives the EFL Championship trophy, which was the previous trophy awarded to the winners of the English top-flight prior to the launch of the Premier League. As with other divisions of professional English football, Welsh clubs can be part of this division, thus making it a cross-border league.
Each season, the two top-finishing teams in the Championship are automatically promoted to the Premier League. The teams that finish the season in 3rd to 6th place enter a playoff tournament, with the winner also gaining promotion to the Premier League. The three lowest-finishing teams in the Championship are relegated to League One.
The Championship is the wealthiest non-top-flight football division in the world, the ninth-richest division in Europe, and the 12th best-attended division in world football (with the second highest per-match attendance of any secondary league – after the German 2.Bundesliga). Its average match attendance for the 2022–23 season was 18,787.
Cardiff City have spent more seasons in this division than any other team, and Bristol City, Preston North End and Queens Park Rangers currently hold the longest tenure in this division, having last been absent in the 2014–15 season. Barnsley became the first club to attain 1,000 wins in second-tier English league football with a 2–1 home victory over Coventry City on 3 January 2011. They also became the first club to play 3,000 games in second-level English league football following another 2–1 home victory, this time against Brighton & Hove Albion on 12 March 2013 The current champions of the league are Leicester City.
Sunderland won the league in the first season since rebranding, with Wigan Athletic finishing second to win promotion to the top flight of English football for the first time in their history. They had only been elected to the Football League in 1978 playing in the fourth tier as recently as 1994 before their promotion. West Ham United won the first Championship play-off final that season, following a 1–0 victory over Preston North End at the Millennium Stadium in Cardiff. The 2004–05 season saw the division announce a total attendance (including postseason) of 9.8 million, the fourth-highest total attendance for a European football division, behind the Premier League (12.88 million), Spain's La Liga (11.57 million) and Germany's Bundesliga (10.92 million). Additionally, Millwall, competing in the inaugural Championship season, qualified for the UEFA Cup, only to lose in the first qualifying round. In the 2005–06 season, Reading broke the Football League points record for a season, finishing with 106 points, exceeding the record of 105 set by Sunderland in 1999.
Sunderland won their second Championship title in the 2006–07 season, after being relegated from the top division the previous season. On 4 May 2007, Leeds United became the first side since the re-branding of the division to enter administration; they were deducted 10 points and were relegated as a result. On 28 May 2007, Derby County won the first Championship play-off final at the new Wembley Stadium, beating West Bromwich Albion 1–0. West Brom would go on to win the Championship in the following season.

On 16 March 2010, npower were announced as the new title sponsors of the Football League, and from the start of the 2010–11 Football League season until the end of the 2012–13 season, the Football League Championship was known as the Npower Championship. Crystal Palace became the second Championship club to enter administration in 2010.
After winning the 2011 League Cup final, Birmingham City became the first Championship club to compete in the group stage of the UEFA Cup/Europa League, finishing third in the group, only one point behind Portuguese club Braga. Birmingham City eventually finished fourth in the Championship that season, and would lose to fifth-place Blackpool in the play-off. Wigan Athletic became the second club to participate in the Europa League group stage after winning the 2013 FA Cup, only to accumulate one win and lose their last three group matches.

For the 2016–17 season, the Football League was rebranded as the English Football League. The league had a cumulative attendance of more than 11 million – excluding play-off matches – with more than two million watching Newcastle United and Aston Villa home fixtures alone, both of whom had been relegated from the Premier League in the previous season. This was included in the highest crowds for the second to fourth tier in England since the 1958–59 season. Newcastle won the title in 2016–17, while Aston Villa finished 13th, eventually returning to the Premier League in 2019.
