The Daimler-Benz DB 604 was an experimental German 24-cylinder aircraft engine, which did not progress beyond the initial engine testing phase and was ultimately abandoned in 1942.

The short stroke ratio enabled the relatively high engine speed of 3,200 rpm.

The DB 604A/B was equipped with a two-speed supercharger, achieving 1,835 kW (2,500 hp) whilst testing.

Development of the DB 604 was canceled by the Reich Air Ministry (RLM - German: Reichsluftfahrtministerium) in September 1942.

A preserved Daimler-Benz DB 604 is on public display at the Flugausstellung L.+ P. Junior museum, Hermeskeil, Germany.
