Trolleybuses in Newcastle upon Tyne

The Newcastle upon Tyne trolleybus system once served the city of Newcastle upon Tyne in England. Opened in 1935, it gradually replaced the Newcastle tram network.

By the standards of the various now-defunct trolleybus systems in the United Kingdom, the Newcastle system was a large one, with a total of 28 routes, and a maximum fleet of 204 trolleybuses. It finished on October 2, 1966.

Two of the distinctive yellow-liveried former Newcastle trolleybuses are now preserved, one at the East Anglia Transport Museum at Carlton Colville, Suffolk, and the other LTN 501 at Beamish Open Air Museum sometimes on loan to The Trolleybus Museum at Sandtoft, Lincolnshire.
