The Stockholm municipal election of 1985 was held on 15 September 1985 concurrently with the 1985 Swedish parliamentary election. This election used a party-list proportional representation system to allocate the 101 seats of the Stockholm City Council (Stockholms stadsfullmäktige) amongst the various Swedish political parties. Voter turnout was 85.2%.
The Swedish Centre Party received only 2.9% of the votes in this election, less than half of the 6.3% they received in 1982, and thus the Centre Party was not allocated any seats as a result of this election. This marks their first failure to achieve a mandate since they first entered the Stockholm City Council in 1966.
