The 2026 Winchester City Council election will be held on 7 May 2026, alongside the other local elections across the United Kingdom being held on the same day, to elect 16 of 32 members of Winchester City Council in Hampshire, England.
Due to ongoing local government reorganisation, this will be the final election to Winchester City Council before it is abolished and replaced by a successor unitary authority. Elections to the successor authority are due to take place in 2027.
In 2024, the Liberal Democrats retained control of the council with an increased majority.
