The 1946 FIBA European Championship, commonly called FIBA EuroBasket 1946, was the fourth FIBA EuroBasket regional basketball championship, held by FIBA and the first since 1939 due to World War II. Ten national teams affiliated with the International Basketball Federation (FIBA) took part in the competition. Switzerland hosted the tournament for a second time, as the championship returned to Geneva.
EuroBasket 1946 saw the beginning of the use of the jump shot, pioneered by Italy's Giuseppe Stefanini.
The 1946 competition consisted of a preliminary round, with one group of four teams and two groups of three teams each. Each team played the other teams in its group once. The top team in each of the groups of three and the top two teams in the group of four played in the semifinals for the top four rankings; the middle teams in the two groups of three moved directly on to the final round for a 5th/6th place playoff; the bottom team in each group of three and the two bottom teams in the group of four played in semifinals for the 7th–10th ranks.
