Jehudi Ashmun was an American religious leader and social reformer from New England who helped lead efforts by the American Colonization Society to "repatriate" African Americans to a colony in West Africa. It founded the colony of Liberia in West Africa as a place to resettle free people of color from the United States.

The American Colonization Society (ACS), initially the Society for the Colonization of Free People of Color of America, was an American organization founded in 1816 by Robert Finley to encourage and support the repatriation of freeborn people of color and emancipated slaves to the continent of Africa. It was modeled on an earlier British colonization in Africa, which had sought to resettle London's "black poor".
