George Hume Steuart, (1700–1784) was a Scottish physician, tobacco planter, and Loyalist politician in colonial Maryland. Born in Perthshire, Steuart emigrated to Maryland in around 1721, where he benefited from proprietarial patronage and was appointed to a number of colonial offices, eventually becoming a wealthy landowner with estates in both Maryland and Scotland, and serving two terms as mayor of Annapolis. However, he was forced by the outbreak of the American Revolution to decide whether to remain loyal to the Crown or to throw in his lot with the American rebels. In 1775 Steuart sailed to Scotland, deciding at age 75 that "he could not turn rebel in his old age". He remained there until his death in 1784.

The Annapolis Subscription Plate is the name given both to the first recorded formal horse race in colonial Maryland and to the silver trophy awarded to the winner of the race. It is the second oldest known horse racing trophy in America.
