The 2026 Richmond upon Thames London Borough Council election took place on 7 May 2026. All 54 members of Richmond upon Thames London Borough Council were elected. The elections took place alongside local elections in the other London boroughs and elections to local authorities across the United Kingdom.
The Liberal Democrats, who have controlled the council since the 2018 election, and increased their majority in the 2022 election, once again increased their majority to become the only party on the council, taking all 54 seats. The opposition Green Party and Conservative Party were thus left without representation, however Conservatives had previously lost their sole seat in a by-election in 2024.
