Elections for Oxford City Council were held on Thursday 4 May 2006. As Oxford City Council is elected by halves, one seat in each of the 24 wards was up for election. The exception was St Clement's, where both seats were up for election as a by-election for the other seat was held on the same day. Therefore, 25 of the 48 seats on the Council were up for election. Overall turnout was 35.8%, down from 37.6% in 2004. The lowest turnout (24.9%) was in Carfax ward and the highest (49.6%) in Marston.
