Atalanta Bergamasca Calcio (Italian: [ataˈlanta berɡaˈmaska ˈkaltʃo]), commonly referred to as Atalanta, is an Italian professional football club based in Bergamo, Lombardy, Italy, who compete in Serie A, the top tier of the Italian league system. Founded in 1907, Atalanta holds the record for having played the most Serie A seasons (64) without being based in a regional capital and without having won the league title. Furthermore, the club holds the record for most promotions to the Serie A, and also that for the joint-most Serie B titles, alongside Genoa.
Atalanta won the Coppa Italia in 1963 and the UEFA Europa League in 2024. The club qualified for the UEFA Champions League four times, reaching the quarter-finals in 2020, and participated in six seasons of the UEFA Europa League (previously known as the UEFA Cup). Atalanta also reached the semi-finals of the Cup Winners' Cup in 1988, when it was competing in Serie B. This is still the joint-best performance ever by a non-first division club in a major UEFA competition.
The club plays its home games at the New Balance Arena and its main kit colors are black and blue. Atalanta had a long-standing rivalry with nearby club Brescia Calcio until that team's dissolution in 2025; the rivalry continues with Brescia's phoenix club, Union Brescia. The club is also famed for its youth academy, which has produced several notable talents who have played in the top leagues of Europe.
