Elections to OxfordCity Council were held on 10 June 2004. The council is elected by halves, so one seat in each ward was up for election (except in St Clements, where both seats were contested). Labour lost majority control of the council but remained in minority administration. Overall turnout was 37.6%, with the lowest turnout (26.5%) in Carfax ward and the highest (49.5%) in Wolvercote.
Because both seats were up for election each voter had two votes (i.e. plurality-at-large). Turnout has been estimated by halving the number of votes cast.
