The 2023 Swale Borough Council election took place on 4 May 2023 to elect members of Swale Borough Council in Kent, England. This was on the same day as other local elections across England.
The council was under no overall control prior to the election. The Conservatives were the largest party, but the council was being run by a rainbow coalition of all the other main parties, led by Mike Baldock of local party the Swale Independents. The council remained under no overall control after the election, and Labour overtook the Conservatives to become the largest party. A new coalition of Labour, the Swale Independents and Greens formed. The new Labour group leader, Tim Gibson, was appointed leader of the council at the subsequent annual council meeting on 17 May 2023, with Mike Baldock becoming deputy leader.
