AFC Bournemouth (/ˈbɔːrnməθ/ ^ⓘ BORN-məth) is a professional association football club based in Kings Park, Boscombe, a suburb of Bournemouth, Dorset, England. The club compete in the Premier League, the top tier of English football. Formed in 1899 as Boscombe, the club adopted their current name in 1971. Nicknamed "The Cherries", and commonly referred to as Bournemouth, they have played their home games at Dean Court since 1910.

The club competed in regional football leagues before going up from the Hampshire League to the Southern League in 1920. By then known as Bournemouth & Boscombe Athletic, they were elected into the Football League in 1923. They remained in the Third Division South for 35 years, winning the Third Division South Cup in 1946. Placed in the newly reorganised Third Division in 1958, they suffered relegation in 1970, but would win an immediate promotion in 1970–71. Relegated back into the Fourth Division in 1975, Bournemouth were promoted again in 1981–82 and after lifting the Associate Members' Cup in 1984 would go on to win the Third Division title in 1986–87. They spent three seasons in the second tier but entered administration in 1997 and ended up back in the fourth tier with relegation in 2002, though immediately gained promotion by winning the play-offs in 2003.

Bournemouth entered administration for a second time and were relegated back into League Two in 2008, but ended the year by appointing Eddie Howe as manager. Under Howe's stewardship, Bournemouth won three promotions in six years to win a place in the first tier of English football for the first time in their history. This was achieved with a second-place finish in League Two in 2009–10, a second-place finish in League One in 2012–13 and a Championship title in 2014–15. The club remained in the Premier League for five seasons before suffering relegation in 2020, but they returned in 2022 as Championship runners-up, this time under the management of Scott Parker.

Although the exact date of the club's foundation is not known, there is proof that it was formed in the autumn of 1899 out of the remains of the older Boscombe St. John's Institute Football Club. The club was originally known as Boscombe Football Club. The first president was Mr. J. C. Nutt.

In their first season, 1899–1900, Boscombe competed in the Bournemouth and District Junior League. They also played in the Hants Junior Cup. During the first two seasons, they played on a football pitch in Castlemain Avenue, Pokesdown. From their third season, the team played on a pitch in King's Park. In the 1905–06 season, Boscombe graduated to senior amateur football.

In 1910, the club was granted a long lease over some wasteland next to Kings Park as the club's football ground by local businessman J.E. Cooper-Dean. With their own ground, named Dean Court after the benefactor, the club continued to thrive, and dominated the local football scene. The same year the club signed its first professional player Baven Penton.

Around about this time, the club obtained their nickname "The Cherries". There are two leading explanations of how the club gained the nickname: from the cherry-red striped shirts that the team played in, and, perhaps less plausible, because Dean Court was built adjacent to the Cooper-Dean estate, which, it is believed, may have contained many cherry trees.

For the first time, during the 1913–14 season, the club competed in the FA Cup. The club's progress, however, was halted in 1914 with the outbreak of World War I, and Boscombe returned to the Hampshire League.^{[citation needed]}
