OB I Bajnokság

The Országos Bajnokság I (Nationwide Championship; commonly abbreviated OB I) is the highest level hockey league in Hungary.

After the formation of the MOL Liga, the OB I returned to having only Hungarian teams. The regular season coincides with the games played between the Hungarian teams in the MOL Liga, with these games also counting towards the national championship. The best three teams advance to the play-offs of OB I, where Alba Volán Székesfehérvár joins them as the fourth team.
