Rīgas Armijas Sporta Klubs was a professional basketball club that was based in Riga, Latvia.

Rīgas ASK was founded in 1931, and started playing in the Latvian Basketball Championship.

[1] Almost immediately, Gomelsky led ASK to the top of the USSR League, as he and the club's star player, Jānis Krūmiņš, led them to USSR League championships in 1955, 1957, and 1958,[2] and also to the top of the European-wide top-tier level, by winning the FIBA European Champions Cup (now called EuroLeague) three times in a row, in 1958, 1959, and 1960.

[6] In 2004, a new club, under the name of BK Rīga was founded; and in 2006, it was renamed to ASK Rīga, after gaining the support of Riga City Council, the National Latvian Army Forces, and some powerful sponsors.
