Mary Ella Forrester Mossell (May 22, 1853 – June 29, 1886) was an American African Methodist Episcopal missionary in Haiti.

She taught Sunday school, opened a day school, formed a Christian Musical Association which performed concerts, sang French translations of religious songs, and held a concert to raise funds to send five converts (including future AME Bishop John Hurst (1863-1930)) to study for the ministry at Wilberforce University.

Her musical and linguistic talents allowed her do outreach to the Haitian elite, including composing original works in French and Creole that have, unfortunately, mostly been lost.

Armed men - accounts differ as to whether they were rebels or government soldiers - killed many people taking refuge with the Mossell's, set fire to their home, and dragged off Rev.

Somehow, a pregnant Mary Mossell was able to prevent them from killing her husband, and with assistance reached the American consulate.
