Constitutional Assembly elections were held in the Kingdom of Serbs, Croats and Slovenes on 28 November 1920.

[1] Deputies are elected by secret ballot, in a direct manner, by the electoral quotient system.

Shortly after the election, the Communist Party of Yugoslavia was banned by the authorities starting with the Obznana.

Up until the elections a Provisional Assembly had existed of unelected delegates from each of the constituent regions of the country.

The electoral districts corresponded to administrative divisions of the constitutive lands which came together to form the Kingdom in late 1918.
