Atalanta Bergamasca Calcio, commonly known as just Atalanta, Atalanta Bergamo or the abbreviation Atalanta BC, is an Italian football club based in Bergamo, Lombardy. The club currently plays in Serie A, having gained the promotion from Serie B in 2010–11. They are nicknamed the Nerazzurri and the Orobici. Atalanta play in blue-and-black vertically striped shirts, black shorts and black socks. The club stadium is the 26,638 seater Atleti Azzurri d'Italia. In Italy, Atalanta is sometimes called Regina delle provinciali (queen of the provincial clubs) to mark the fact that the club is historically one of the most consistent among the non-metropolitan ones, having played 53 times in Serie A (11th overall for number of participations in the top division), 28 times in Serie B and only once in Serie C1. The club won the Coppa Italia in 1963 and reached the Cup Winners' Cup Semifinal in 1988, when it was still competing in Serie B. This is still the best ever performance by a non-first division club in a major UEFA competition (together with Cardiff City). Atalanta also participated twice in the UEFA Cup, reaching the quarterfinals in 1990–91.

The New Balance Arena, known as the Stadio di Bergamo in UEFA competitions, is a stadium in Bergamo, Italy. It is the home of Serie A club Atalanta and has a capacity of 23,439 seats. The field is 120 m (130 yd) long and 70 m (77 yd) wide. Atalanta has owned the stadium since 2017, having purchased it from the comune. Atalanta's under-23 team and youth team sometimes play competitive matches at the stadium. The stadium in Bergamo has also been used as a home ground by local club AlbinoLeffe from 2003 to 2019 (when it moved to Gorgonzola)—a period during which AlbinoLeffe spent nine years in Serie B and met Atalanta on several occasions—and for various matches of the Italy national team.
