The election for Southwark London Borough Council took place on 3 May 2018, the same day as for other London Boroughs. All 63 seats were up for election.
New boundaries were used, using 23 two- and three-member wards (there were previously 21 three-member wards), following a Local Government Boundary Commission for England review that concluded in 2016. The review reflected demographic growth, shifting seats from the south of the borough to its northwest.
