Trondheim Trafikkselskap or TT was the city public transport company for Trondheim, Norway between 1974 and 2001. It operated both the city buses, and the Trondheim Tramway until 1988. The company was owned by the city council.
TT was founded in 1972 as a merger between the municipal-owned tramway companies Trondheim Sporvei and Graakalbanen, and the bus company Bynesruten. In 1974, the company was reorganized as a municipal agency, and also took over the private bus operator Trondheim Bilruter, along with the city bus lines of Klæburuten and NSB Bilruter. In 2001, the company merged with Hemne og Orkladal Billag to create Team Trafikk, that was later sold to Nettbuss.
