The 2025 Oxfordshire County Council election was held on 1 May 2025 to elect members to Oxfordshire County Council in Oxfordshire, England. All 69 seats were elected. This was on the same day as a by-election for the Oxford City Council ward of Headington Hill and Northway, as well as other local elections nationwide. The council had been under no overall control prior to the election, being run by a Liberal Democrat and Green Party coalition, led by Liberal Democrat councillor Liz Leffman. The election saw the Liberal Democrats win overall control of the council for the first time.
The council had been under no overall control since 2013. Following the previous full council election in 2021, a coalition of the Liberal Democrats, Labour, and the Green Party formed to run the council, led by Liberal Democrat councillor Liz Leffman. Labour withdrew from the coalition in September 2023, after which the Liberal Democrats and Greens ran the council as a minority administration.
The 2025 election was held under new ward boundaries.
