1973 Newcastle City Council election

The first elections to the newly created Newcastle City Council were held on 10 May 1973, with the entirety of the 78 seat council - three seats for each of the 26 wards - up for vote. The Local Government Act 1972 stipulated that the elected members were to shadow and eventually take over from the predecessor corporation on 1 April 1974. The order in which the councillors were elected dictated their term serving, with third-place candidates serving two years and up for re-election in 1975, second-placed three years expiring in 1976 and 1st-placed five years until 1978.

The election resulted in Labour gaining control of the council. Voter turnout was 32.0%.
