The Drammen trolleybus system was a system of trolleybuses in Drammen, Norway, which operated between 15 December 1909 and 10 June 1967. The system stretched from the city center to Brakerøya, Merket and Vårveien and was operated by the companies Drammens Elektriske Bane, A/S Trikken and Drammen Kommunale Trikk. The system was well suited for Drammen, since the city has a lot of hills and cheap electricity.
