1945 Országos Bajnokság I (men's water polo)

The 1945 Országos Bajnokság I was the top-level championship for men's water polo in Hungary during the year 1945. It was the 39th edition of the Hungarian Water Polo Championship. Due to the ongoing effects of World War II, the structure and participation in the league may have been impacted, but information regarding specific teams and match details are scarce. Generally, Országos Bajnokság I (OB I) represented the highest level of competitive water polo in Hungary, and the winner of the tournament was recognized as the national champion. The historical context of the competition being held so soon after the end of the war is significant, highlighting the continued importance of sport within Hungarian society during a period of rebuilding. Further research is needed to confirm specific team names, final standings, and any rule modifications that may have been in place that year.
