Butler's Rangers (1777–1784) was a British provincial regiment composed of Loyalists (or "Tories") in the American Revolutionary War, raised by Loyalist John Butler. Most members of the regiment were Loyalists from upstate New York. Among the regiment were former black slaves, the total number of black soldiers in Butler's Rangers is unknown, with estimates ranging from two to "more than a dozen". While some blacks served in other units and as sappers in the Engineer Corps and in the Royal Artillery, Sir William Howe banned the enlistment of blacks and ordered the disbanding of existing black regiments.
