Detroit Diesel Corporation (DDC), is a diesel engine producer headquartered in Detroit, Michigan, USA. There are today two individual divisions that share this name: the off-highway division which is owned by Tognum, which EQT Partners formed along with MTU Friedrichshafen, and the on-highway division which is owned by Daimler AG.

Detroit Diesel was part of the Freightliner - Trucks NAFTA Business Unit of DaimlerChrysler (now Daimler AG and Chrysler LLC respectively) until it was split into two. The on-highway part of Detroit Diesel remains a part of this division, with the sale of the off-highway division to EQT IV.

The company produces on-highway medium and heavy-duty Diesel engines for the commercial truck market, and for other commercial and automobile use. Engines range from 170 to 560 hp (127 to 418kW) for the on-highway market. The Series 60 has been the market share leader since 1992, and combined with the MBE 4000 has 27% of the Class 8 market. Worldwide there are over 800,000 Series 60's, and over 350,000 MBE 900's, in operation.
