The 1926 National Championship (Serbo-Croato-Slovenian: Državno prvenstvo 1926 / Државно првенство 1926) was a football competition held within the Kingdom of Serbs, Croats, and Slovenes. The two dominant teams of pre-World War II Yugoslav football, Jugoslavija and Građanski, began laying the foundations of the next seven decades of a deeply rooted rivalry between Zagreb and Belgrade. Both teams dominated the competition with comfortable margins, but were quite evenly matched in the finals.
