Christopher Dufrost de La Jemeraye (also known as Christophe Dufrost de La Jemerais with various variations on the last name),(b. December 6, 1708 – d. May 10, 1736), was the lieutenant and nephew of Pierre Gaultier de Varennes et de La Vérendrye in the exploratory party that headed west from Fort Kaministiquia, Ontario, Canada, in 1731. He and Jean Baptiste de La Vérendrye established Fort St. Charles on Lake of the Woods in 1732. In the spring of 1733, he and Jean Baptiste headed down the Winnipeg River to set up a post in the Lake Winnipeg area. They were stopped by ice and La Jemeraye returned to Fort St. Charles while his cousin established a small temporary fort named La Barrière.
