Rosina Tucker was an American labor organizer, civil rights activist, and educator. She is best known for helping to organize the Brotherhood of Sleeping Car Porters, the first African-American trade union. Since porters worked long hours and were afraid of reprisals, Tucker and other wives of porters did a lot of organizing for the Brotherhood of Sleeping Car Porters. Rosina helped organize Ladies' Auxiliary, which raised funds for the union by hosting community events. Outside of her work with Brotherhood of Sleeping Car Porters, Rosina helped organize teachers and laundry workers in the Washington D.C area, and helped organize the 1963 March on Washington.
