The Elfin MR5 is an Australian Formula 5000 racing car produced from 1971-1972 by Elfin Sports Cars.

Designed by Elfin owner/driver Garrie Cooper, the MR5 was the first car built by Elfin for Formula 5000 racing which had formed the basis of Australia's top open-wheel category, Australian Formula 1, from 1971. A total of four MR5's were built and the cars were powered by Repco-Holden 5.0L V8 or Ford V8 engines.

John McCormack drove an MR5 to victory in the 1973 Australian Drivers' Championship,[1] the 1973 New Zealand Grand Prix, the 1974 New Zealand Grand Prix and the 1974 Lady Wigram Trophy.[4]
