The 1927 National Championship (Serbo-Croato-Slovenian: Državno prvenstvo 1927. / Државно првенство 1927.) was the first year in which the championship was played in a league system, with Hajduk Split being the first national league champion. Newcomer BSK Beograd replaced Jugoslavija Beograd as Serbia's top-performing club, this was due to half of the Jugoslavija players switching clubs to play for BSK. Hajduk and second-place club BSK entered the 1927 Mitropa Cup.
For the final stage of the national championship, the clubs were qualified through their subassociation competitions, although this year, the major subassociations of Belgrade and Zagreb gave each two teams for the qualifying stage, qualifying the subassociation champions directly, while the second placed will participate in a qualifying round. Hajduk Split also qualified directly as Cup winner, while the champions of the rest of the subassociations played the qualifying round.

Qualifying round:
The qualified teams were Ilirija, SAŠK and SAND. The elimination of Građanski and Jugoslavija, both former national champions, was a major surprise. The qualification was played only in one round. As Hajduk Osijek and SAND ended tied in their match, an additional match between them was played in Osijek on May 30 which qualified SAND.[1]
