The 2023 King's Lynn and West Norfolk Borough Council election took place on 4 May 2023 to elect members of King's Lynn and West Norfolk Borough Council in Norfolk, England. This was on the same day as other local elections in England.
Prior to the election the council was under Conservative majority control. Following the election the Conservatives remained the largest party but lost their majority, leaving the council under no overall control. A coalition of the independent councillors, Liberal Democrats and Greens formed a minority administration with informal support from Labour, with independent councillor Terry Parish being appointed leader of the council at the subsequent annual council meeting on 18 May 2023. A few days after the elections, unseated councillor and former mayor David Whitby passed away.

The results for each ward were as follows, with an asterisk (*) indicating an incumbent councillor standing for re-election:
