The Ipswich trolleybus system once served Ipswich, the county town of Suffolk, England. Opened on 2 September 1923, it gradually replaced the Ipswich tramway network. By the standards of the various now-defunct trolleybus systems in the United Kingdom, the Ipswich system was a medium-sized one, with a total of 14 routes, and a maximum fleet of 85 trolleybuses. The system was closed on 23 August 1963. In 1962, eight of its newest trolleybuses were sold to Walsall for further service; most of these survived until 1970.
