Count Gaston de Chasseloup-Laubat (1866, 7 June Paris, France - 20 November 1903, Le Cannet, France) was a French and race car driver. He was the son of Prosper, Marquis of Chasseloup-Laubat, minister of Napoleon III, and of his American wife Marie-Louise Pilié.
He is known for setting the first recognised automobile land speed record on December 18, 1898 in Achères, Yvelines, using a Jeantaud electric car. The record was set as part of a competition organised by the French automobile magazine La France Automobile. He completed a single flying 1 kilometre (0.62 mi) run in 57 seconds to give an average speed of 63.13 km/h (39 mph)
He further improved this record to 66.65 km/h (41.41 mph) one month later on January 17, 1899, also at Achères in the first of a series of record setting duels with Camille Jenatzy. Ten days later Jenatzy managed to break this record although it would revert to de Chasseloup-Laubat on March 4, 1899 when he increased it to 92.69 km/h (57.59 mph). Jenatzy finally took the record on April 29, 1899 with the first run over 100 km/h (62 mph) with an average speed of 105 km/h (65 mph), a record that was to last 3 years.
Chasseloup-Laubat managed to win the Marseille-La Turbie long-distance race in 1897 with a steam vehicle built by Trépardoux & Cie, predecessor of De Dion-Bouton. This was the only mayor city-to-city event won by a steam car.
The count died in Le Cannet, near Cannes, aged 37, after a two-years long illness.
