Uruguay - Primera División

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. Some of the other League champions were: Salto Uruguay in 2004, Trouville in 2005–06, Malvín in 2006–07 and 2010–11, Biguá in 2007–08 and 2008–09, Hebraica Macabi in 2011–12, and Aguada in 2012–13. So far, there are only two teams that have appeared in all of the league's seasons; they are: Defensor Sporting and Trouville.
