George Croghan (c. 1718 – August 31, 1782) was an Irish-born fur trader in the Ohio Country of North America (current United States) who became a key early figure in the region. In 1746 he was appointed to the Haudenosaunee Onondaga Council and remained so until he was banished from the frontier in 1777 during the American Revolutionary War. Emigrating from Ireland to Pennsylvania in 1741, he had become an important trader by going to the villages of Indigenous Peoples, learning their languages and customs, and working on the frontier where previously mostly French had been trading. During and after King George's War of the 1740s, he helped negotiate new treaties and alliances for the British with Native Americans.
