The Hungary men's national water polo team are considered the world's top power in the history of water polo, having won 15 Olympic, 10 World Championship, 5 FINA World League, 8 FINA World Cup and 21 European Championship medals. Hungary missed only one European Championship, in 1950, and they have won the tournament 12 times, which is (as in the World Championships) a record. No team has a better result than Hungary in history of the European Championship.
