Janis Kruminš (30 January 1930 – 20 November 1994) was a Soviet-Latvian professional basketball player.
Helped by his height (about 220 cm, or 7'3"), he was the first giant center that dominated under European baskets, for years.
As a player of the senior Soviet Union national basketball team, Kruminš won 3 gold medals at the 1959, 1961, and 1963 EuroBaskets, as well as 3 silver medals at the 1956, 1960, and 1964 Summer Olympic Games.
A Russian poll that was conducted in 2006, named Kruminš as the 3rd most popular Soviet men's basketball player of all time, after Arvydas Sabonis and Vladimir Tkachenko.
