Charles Guillimin (1676 – February 27, 1739) was a Canadian entrepreneur.
Guillimin arrived in New France in the late 17th century with enough capital to pursue a number of enterprises, including ship building, outfitting of ships, and a variety of mercantile endeavours. In 1712, he loaned the king's treasury a large sum of money to avert a financial crisis.
Guillimin had numerous close ties within the Canadian business community both through marriage and business connections. His largesse of 1712 brought recognition by his installation as a councillor in the Conseil Supérieur of New France. He was singled out for praise by Governor Charles de Beauharnois and Intendant Gilles Hocquart. His fortune disappeared later in life.
