Trolleybuses in Darlington

The Darlington trolleybus system once served the town of Darlington, County Durham, England. Opened on 17 January 1926 (1926-01-17), it replaced the Darlington Corporation Light Railways tramway network.

By the standards of the various now-defunct trolleybus systems in the United Kingdom, the Darlington system was a moderately sized one, with a total of 5 routes, and a maximum fleet of 66 trolleybuses. It was closed relatively early, on 31 July 1957 (1957-07-31).

None of the former Darlington trolleybuses are recorded as having been preserved.
