The Walsall trolleybus system once served the town of Walsall, then in Staffordshire, but now in West Midlands, England. Opened on 22 July 1931, it gradually replaced the Walsall Corporation Tramways network. By the standards of the various now defunct trolleybus systems in the United Kingdom, the Walsall system was a medium-sized one, with a total of 6 routes, and a maximum fleet of 60 trolleybuses. It was also one of the last to be closed, on 3 October 1970.
