Barca CBS Women

Founded on 24 August 1926, the club entered its first competition in 1927, playing in the Campionat de Catalunya de Basquetbol (Catalan Basketball Championship). During these early years, basketball in Catalonia was dominated by clubs such as CE Europa, Laietà BC and Société Patrie (later CB Atlètic Gràcia) and it was not until the 1940s that FC Barcelona became established as a basketball team. During this decade they won six Copas del Generalísimo de Baloncesto and were runners-up once. In 1956 they were founding members of the Liga Española de Baloncesto and finished as runners-up. In 1959 they won Spanish basketball's first-ever league and cup double.

The 1960s and 1970s saw the team in decline. In 1961 the club president Enric Llaudet dissolved the team in spite of its popularity. However, in 1962, the club was reformed after a campaign by the fans. In 1964 the league's Primera División was cut from fourteen teams to eight and the club found themselves in the Segunda División after not finishing between the two first qualified teams in the relegation playoffs. However they quickly returned to the top division after being crowned Segunda champions in 1965. During the 1970s the club was persistently overshadowed by its rivals Real Madrid and Joventut.

In the 1980s club president Josep Lluís Núñez gave the team his full support with the aim of making the club the best in Spain and Europe. His support produced results and during the decade inspired by their coach Aíto García Reneses and players like Juan Antonio San Epifanio (better known as Epi), Andrés Jiménez, Sibilio, Audie Norris and Solozábal, the club won six Spanish championships, five Spanish cups, two European Cup Winners' Cups, the Korać Cup and the World Championship. However the European Cup remained elusive, ending as runners-up in 1984. In the 1987–88 season Barça won the Copa Príncipe, Liga ACB, Copa del Rey and the Supercopa completing a quadruple.

The club built on this success during the 1990s, winning a further four Spanish championships and two Spanish cups. They were still unable to win the European Cup despite playing in a further four finals in 1990, 1991, 1996 and 1997. They also made a record six EuroLeague Final Four appearances. The star player during this era was Juan Antonio San Epifanio.

Their persistence eventually paid off and in 2003, inspired by Dejan Bodiroga, Gregor Fučka, Šarūnas Jasikevičius and Juan Carlos Navarro, they won the EuroLeague, beating Benetton Treviso 76–65 in front of a packed Palau Sant Jordi in Barcelona. They repeated the feat in 2010, defeating Olympiacos by a wide 86–68 in Paris, and that October, they made further history when they beat the two-time defending NBA champion Los Angeles Lakers – including Kobe Bryant and FCB Bàsquet alumnus and Barcelona native Pau Gasol – 92–88 at the Palau Sant Jordi as part of the 2010 NBA Europe Live Tour. The match was also notable for being both a match-up between the reigning NBA and EuroLeague champions and the first time a European team had won against a defending NBA champion. Two FCB Bàsquet players in that game – captain Navarro and point guard Ricky Rubio – either had or went on to play in the NBA.

In the following years, Barcelona would stay on top of Spanish basketball, playing almost all league and cup finals against rival Real Madrid. From 2012 until 2014, Barcelona managed to reach the Euroleague Final Four. However, it could not reach further than the semifinals. Barcelona won the Spanish Championship in 2014, but the next few seasons became absolute disasters, both in the Euroleague, and the Spanish League. However, the team saw a return to form in the Copa del Rey, which was won in 2018, in 2019 and in 2021 defeating Real Madrid on all three finals. In 2021 the Spanish Championship was won for the 19th time—the first in seven years—and only a narrow defeat against Anadolu Efes in the championship game of the 2021 EuroLeague Final Four prevented the Catalan giants from winning the competition for the third time. On June 21 2023 Barça defeated Real Madrid 82–93 to win their 20th Spanish Championship.
