The 1923 National Championship (Serbo-Croato-Slovenian: Državno prvenstvo 1923. / Државно првенство 1923.) held in the Kingdom of Serbs, Croats and Slovenes was the first nationwide domestic football competition. At this point there was no league championship in the modern sense as the competition was held in a single-legged cup format, with participating clubs qualifying via regional playoffs organised by the existing 6 regional football subfederations.
