Burnley Football Club () is a professional football club based in Burnley, Lancashire, England. The club will compete in the Premier League in 2025–26 following promotion in the 2024–25 EFL Championship season. Founded in 1882, Burnley were one of the first to become professional (in 1883) and subsequently put pressure on the Football Association to permit payments to players. They entered the FA Cup for the first time in 1885–86 and were one of the 12 founder members of the Football League in 1888–89, the world's first league football competition.

Burnley are one of only five sides to have won all four professional divisions of English football, and have twice been crowned champions of England, in 1920–21 and 1959–60. They have won the FA Cup once, in 1913–14, and have won the FA Charity Shield twice, in 1960 and 1973. The team have also finished as runners-up in both the First Division and FA Cup on two occasions. During the 1920–21 campaign, Burnley embarked on a 30-match unbeaten league run, setting an English record. From the 1950s until the 1970s, under chairman Bob Lord, Burnley were renowned for their youth policy and scouting system, and were one of the first to set up a purpose-built training ground. The majority of the team that won the 1959–60 league title had progressed through the club's youth academy. At the time, Burnley—with a population of 80,000—became one of the smallest towns to produce an English first-tier champion.

The team have played home games at Turf Moor since 1883, after they had moved from their original premises at Calder Vale. Nicknamed \"The Clarets\", the club colours of claret and blue were adopted in 1910. The club's current emblem is based on the town of Burnley's coat of arms. The side have a long-standing rivalry with nearby club Blackburn Rovers, with whom they contest the East Lancashire Derby. Burnley's record appearance holder is Jerry Dawson, who made 569 appearances in a 22-year playing spell with the team, and their record goalscorer is George Beel with 188 goals.
