1973 North Hertfordshire District Council election

The 1973 North Hertfordshire District Council election was held on 7 June 1973. It was the first election to North Hertfordshire District Council, and was held at the same time as other local elections across England for the new non-metropolitan district councils that were created under the Local Government Act 1972. The elected councillors initially formed a shadow authority to oversee the transition to the new system, operating alongside the five outgoing district councils until 1 April 1974 when the new district formally came into being.

The election saw the Conservatives form the largest party on the council, albeit falling a couple of seats short of having a majority, leaving the council under no overall control. The Conservatives formed a minority administration, with their group leader, Bob Flatman, becoming the first leader of the council.
