Guy Camille Ligier (French pronunciation: [ɡi ka.mij li.ʒje]; 12 July 1930 – 23 August 2015) was a French racing driver and team owner. He maintained many varied and successful careers over the course of his life, including rugby player, butcher, racing driver and Formula One team owner.

He is the father of Philippe and Pascale Ligier and the grand father of Etienne Ligier former French motorsport hopeful.

The son of a farmer, Ligier was orphaned at 7 years of age. He left school in his mid-teens and went to work as a butcher's assistant in his home town of Vichy.

Athletic and competitive, he became a French rowing champion in 1947. He also had a passion for rugby and was good enough to play for the French Army during National Service earning a place on the French national B team. His rugby career was cut short due to injuries.

Determined to become successful, Ligier saved all of the money he earned working as a butcher to fund his aspirations. In 1960, he rented a backhoe and, a short time later, bought a bulldozer of his own and went into the construction business.

With help from Pierre Coulon, Vichy's Mayor, he founded the public works company "Ligier Travaux Publics". With motorway construction booming in France, Ligier was able to rapidly expand his business. By 1961, he had 1200 employees and 500 machines and had also diversified into bridges, dams and development. During this period, his business contacts allowed him to make important friends in (then) local politicians François Mitterrand and Pierre Bérégovoy.

When his rugby career ended, he switched to racing but on motorcycles. He would win the French Motorbike Championship in the 500cc class riding a Norton Manx "LA" in 1959 and in 1960.

Ligier made an early foray into auto racing with a Simca 1300 at the 1957 Parisian Salon Cups in Montlhéry, but it was in 1960 that he first tried his hand at single-seater racing with a Formula Junior Elva-DKW, which he drove at Monaco and Montlhéry.
