T45 is a Swedish diesel-electric locomotive operated by Swedish State Railways (Swedish: Statens Järnvägar, SJ) and later other companies. It was in passenger service with SJ from 1971 to 1976, after which it was used in heavy industry. It is the only diesel locomotive to be built by Allmänna Svenska Elektriska Aktiebolaget (ASEA).

The loco used a SEMT Pielstick diesel engine. ASEA used the same bogies and electrical systems as on the Rc locomotive, while Thune of Norway built the mechanical parts.
