Elections to Chichester District Council in West Sussex, United Kingdom were held on 4 May 2023. The election took place on the same day as other local elections.
The whole council was up for election, having previously been under no overall control and led by a Conservative minority administration. The Conservative leader of the council prior to the election, Eileen Lintill, did not stand for re-election. The Liberal Democrats won 25 seats, the first time that the party (or any other than the Conservative Party) secured a majority on Chichester District Council. Liberal Democrat group leader Adrian Moss was appointed as the new leader of the council at the subsequent annual council meeting on 17 May 2023.
