The Kopanong Local Municipality council consists of seventeen members elected by mixed-member proportional representation.
Nine councillors are elected by first-past-the-post voting in nine wards, while the remaining eight are chosen from party lists so that the total number of party representatives is proportional to the number of votes received.
In the election of 3 August 2016 the African National Congress (ANC) won a majority of eleven seats on the council.
