Politics
The municipal council consists of forty-three members elected by mixed-member proportional representation. Twenty-two councillors are elected by first-past-the-post voting in twenty-two wards, while the remaining twenty-one are chosen from party lists so that the total number of party representatives is proportional to the number of votes received. In the 2016 local government elections, the Democratic Alliance received a majority of thirty seats on the council. The following table shows the results of the 2016 election.

In the local government elections of 2000, the Democratic Alliance came to power in Stellenbosch. The administration was short-lived, however, and in October 2002, an African National Congress and New National Party coalition took over the council when four councillors defected from the DA and a local community party during a floor-crossing period. Willie Ortell was elected mayor and GW Adonis was chosen as deputy mayor. After the next local government elections in 2006, a coalition was formed by the DA and several smaller parties, and Lauretta Maree of the DA was elected as executive mayor and Khulile Shubani of the United Democratic Movement as deputy-mayor. In February 2008 councillor Myra Linders left the DA and stood as an independent candidate in the resulting by-election, and won. Her shift in allegiance allowed an ANC-led coalition, with the swing votes of the two councillors from the Kayamandi Community Alliance to take control of the council in April 2008. Patrick Swartz of the KCA was elected mayor while Cameron Mcako of the ANC became deputy mayor. After serious allegations of fraud by councillors surfaced, Myra Linders once again used her swing vote to topple the administration in December 2009 by supporting a DA-led motion of no-confidence in the mayor, deputy mayor and speaker Gordon Pheiffer of the ANC. Cyril Jooste of the DA became the new mayor, and Mcako and Pheiffer both resigned. In the 2011 local government elections voters handed the DA an outright majority of twenty-five seats on the council, resulting in the first stable municipal council in more than a decade. Conrad Sidego of the DA was appointed the new mayor. In the 2016 local government elections, the DA increased their majority in the council to thirty seats. Gesie van Deventer of the DA was elected as the new mayor.
