Pierre-Louis de Lorimier, usually anglicized to Peter Loramie (March 1748 – June 26, 1812), was a colonial French-Canadian fur trader, British Indian agent, and Shawnee agitator.

He was born in the Saint-Étienne parish of Montreal, Canada, New France, son of Captain Claude Nicholas de Lorimier and Marie Louise Lepailleur.

In 1769, he moved south with his father and established a fur trading post in Shawnee territory in the Great Miami River valley at the confluence of Loramie Creek (later named for him).

In February 1778, Lorimier and another Frenchman, along with chief Blackfish of the Shawnee, led a raid on Boonesborough, Kentucky, which resulted in capturing frontiersman Daniel Boone.

Lorimier lived during a transitional period for the Cape Girardeau area, one in which its national ownership was transferred in rapid succession from Spain to France, and then to the United States via the Louisiana Purchase of 1803.

Cape Girardeau County was first settled by a mix of French-Canadian and Shawnee refugees who had fled with Lorimier from Ohio Country, and soon afterwards moved to the Spanish-held lands west of the Mississippi.
