The Rider-Elmendorf R-5, also known as the Jackrabbit, is a United States racing airplane designed by Keith Rider to compete in the National Air Races in 1936. Rider also developed the R-4 Firecracker for the same season.

The R-5 is a low-wing monoplane with retractable landing gear. Its wing is made of wood with two spars and plywood covering; the fuselage uses welded steel tubing with fabric covering, while the tail surfaces are all metal. The main gear retracts without brakes and uses a simple manual jackscrew, and the aircraft uses a tailskid instead of a tailwheel.

Douglas engineers Hal Marcoux and Jack Bromberg bought the plane, painted it black and yellow, and renamed it the Jackrabbit. The R-5 was later owned by James C. Garvin in 1966 and then by Morton Lester, who displayed it at the EAA Aviation Museum in Oshkosh, Wisconsin.
