Elections for Cambridge City Council were held on Thursday 4 May 2006. As Cambridge City Council is elected by thirds, one seat in each of the city's 14 wards was up for election. The exception was Romsey, where two seats were up for election as a by-election for the other seat was held on the same day. Therefore, 15 of the 42 seats on the council were up for election. Overall turnout was 34.4%, down from 37.0% in 2004. The lowest turnout (28.4%) was in Abbey ward and the highest (40.8%) in Queen Edith's.
