The '''Reggiane Re.2004''' was an Italian single-engined monoplane made by Reggiane and designed by Roberto Longhi. The aircraft never passed the preliminary stages.

==Design and development== The Re.2004 had identical fuselage, wings and other components to the Re.2005. The Re.2004 was powered by an air-cooled Isotta Fraschini Zeta RC 24/60 engine, with 24 cylinders arranged in an X-pattern, producing {{convert|1250|hp|kW|0|abbr=on}}.

In 1942, a prototype was built, and ten models were ordered; the order was later cancelled due to unresolved engine overheating problems.<ref>Alegi, 2001, p.35</ref> However, by this time, the Re.2005 had been completed.
