The 2026 Stevenage Borough 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 13 of 39 members of Stevenage Borough Council in Hertfordshire, England.
In 2024, the Labour Party retained majority control of the council. In January 2026, the council asked for the election to be postponed pending local government reorganisation. However it was rescheduled on 16 February 2026.
