Legislative elections were held in Adjara, an autonomous republic within Georgia, on 31 October 2020. Adjara elected its 21-member parliament, Supreme Council, in the region's 8th local legislative election since Georgia declared independence from the Soviet Union in 1991.
The election was held simultaneously with the nationwide parliamentary election. The 21-member Supreme Council of Adjara is elected for a 4-year term. 3 of its members are elected in single-member constituencies and the remaining 18 seats are filled through proportional representation from parties which clear a 5% threshold.
