DSB class MZ was a series of 61 diesel-electric locomotives operated by Danske Statsbaner. They were built by NOHAB between 1967 and 1978 on licence from General Motors EMD with subcontractors Thrige-Titan (traction motors) and Frichs (chassis, bodywork) .

There were four series of the locomotive built, designated I - IV.

Twenty units became the property of Railion Denmark in 2001, sixteen units of the III series were exported to Australia in the late 2000s, as of 2010 owned by Independent Rail of Australia. As of 2010 most of the remainder of the class are divided between various Danish, Swedish and Norwegian companies.

In sweden the locomotives have received the designation TMZ.

Most locomotives were sold to various Swedish and Norwegian operators between 2003 and 2006 including two units each to BK Tåg, TÅGAB and the Norwegian National Rail Administration (Jernbaneverket), and single units to Motala Verkstad and Svensk Tågteknik AB.[3] Locomotive number MZ 1425 has been rented to Railiom between 2001 and 2003 and in 2004 was equipped with automatic coupling for the transportation of IC4 multiple unit trains.[8]
