Deutz AG is an engine manufacturer, based in Cologne, Germany.

The company was founded by Nikolaus Otto, inventor of the four-stroke internal combustion engine, in 1864 as N. A. Otto & Cie. Other famous names who worked for Deutz are Eugen Langen, Gottlieb Daimler, Wilhelm Maybach, Prosper L'Orange, Rudolf Diesel, Robert Bosch and Ettore Bugatti.

In the early years Otto and his partner, lawyer Eugen Langen, were interested only in stationary engines, not in automobiles. In the middle 1870s, technical director Gottlieb Daimler, agitating for production of automobiles, was transferred to the company's St. Petersburg factory to reduce his influence. He resigned, taking Wilhelm Maybach with him.

Deutz once also produced agricultural machines like combines and tractors as well as commercial vehicles such as lorries and buses. (In 1995 Deutz sold the agricultural machinery division – called Deutz-Fahr – to SAME, an Italian company, which formed SAME Deutz-Fahr then.) Deutz's head office is in the Porz district of Cologne and as of 2004 was manufacturing liquid and air-cooled diesel engines. The larger engines in the Deutz range were manufactured in Mannheim, at a production facility that once belonged to a company called MWM. Deutz also have production facilities in other countries including Spain and a joint venture production facility in China. After Deutz took over, the plant specialised in marine engines. This facility now produces engines for marine and power generation which can run on either fuel oils or fuel gases (including landfill gas).
