The De Tomaso Longchamp is a grand tourer produced in Italy from 1972 to 1989. It was derived from the De Tomaso Deauville 4-door limousine. The Deauville and Longchamp were the only production cars with front-mounted engines produced by De Tomaso.

The Longchamp was first introduced at the 1972 Turin Motor Show. It was sold as a 2-door coupe and convertible. It was rear-wheel drive and was powered by a 5.8-litre V8 engine with 330 hp (246 kW), which was mated to a 3-speed automatic or 5-speed manual transmission. It could reach a top speed of 240 km/h. In total, only 409 examples were produced.
