The Liga Uruguaya de Básquetbol (abbreviated as LUB; English: Uruguayan Basketball League) is the most important professional club basketball league in Uruguay. It is organized by the Uruguayan Basketball Federation (FUBB). The Uruguayan Basketball League competition began in 2003. Before that time, the Uruguayan basketball championships were only local metropolitan, and no competitions brought together all the clubs in the country. Until the Liga Uruguaya de Básquetbol was created, the capital clubs participated in the Campeonato Uruguayo Federal de Básquetbol (Uruguayan Federal Basketball Championship), while the clubs of the rest of the country competed in regional tournaments. The Uruguayan Federal Basketball Championship was founded in 1915, making it among the oldest on the continent.
The first LUB competition had a dramatic end, with a win in the last second, that brought the Uruguayan League title to Defensor Sporting, whom also repeated in the 2009–10 season. So far, Defensor Sporting will be the only one to appear in all of the league's seasons, after the relegation of Trouville in the 2024–25 season.
