The 2023 Runnymede Borough Council election took place on 4 May 2023 to elect one-third of members of the Runnymede Borough Council in Surrey, England. This was on the same day as other local elections in England.
The Conservative Party lost control of the council for the second time since the first election in 1973, the first being a short period between 1996 and 1998 when it was also under no overall control.
