Rochester-Duesenberg is the designation for an automobile engine developed as a racecar engine by the Duesenberg brothers. When the design became obsolete for racing in 1919, they sold the rights and tools for its last iteration, the Duesenberg Model G engine, to the Rochester Motors Company, Inc. (no connection to the former Rochester division of General Motors), which derived a street-legal luxury car engine. There were several variants; Fred S. Duesenberg was involved in some of them.

Typical Rochester-Duesenberg engine is a straight-4 cylinder with the patented Duesenberg "Walking Beam" valve gear.
