The Piratas de Quebradillas is a Puerto Rican basketball team, part of the Baloncesto Superior Nacional (BSN), the top flight of Puerto Rico basketball. Founded in the mid 1920s, it is one of the original teams of the league. The club enjoyed its most successful era during the 1970s, when they won four championships, including a three-peat, and participated in six league finals. However, after the 2004 season, the team suffered from financial problems, which prevented them from participating in the following five seasons. The club returned to active competition in 2009 with new players and a new arena, as well as a trip to the league finals. After a 34 years hiatus, in 2013 they won the BSN championship, defeating the Leones de Ponce in a six game series.
