Robert T. Lincoln Poston (February 25, 1891 – March 16, 1924) was an African-American newspaper editor and journalist, who was an activist in Marcus Garvey's Universal Negro Improvement Association (UNIA).
His father, Ephraim Poston, was a teacher, poet and graduate of Roger Williams University in Nashville, Tennessee, who authored Manual on Parliamentary Proceedings, 1905, and Pastoral Poems, 1906.
Robert and Ulysses were among the co-directors of a play the UNIA dramatic club put on in 1922, entitled "Tallaboo".
Poston and the others met with President King of Liberia, but they were not ultimately able to obtain the permissions and aid that they required.
On March 19, 1924, Poston was posthumously given the rank of Prince of Africa by the UNIA during an elaborate state funeral at Liberty Hall.
