Elijah Johnson (c. 1789[A] – April 3, 1849) was an African American who was one of the first colonial agents of the American Colonization Society in what later became Liberia. He was probably born in New Jersey and received some limited schooling in New Jersey and New York. He served as a soldier in the War of 1812 and studied for the Methodist ministry. In 1835 he led a company of 120 armed volunteers from Monrovia on a punitive expedition to engage King Joe as a result of the Port Cresson massacre.[1][2][3][4] His son Hilary R. W. Johnson was elected in 1884 as President of Liberia, the first to have been born in the country.
