Walter Stewart (1756 – June 16, 1796) was an Irish-born American general in the Continental Army during the American Revolutionary War. Stewart began his military career as captain of a Pennsylvania infantry company at the beginning of the American Revolutionary War. He served as an aide-de-camp to Horatio Gates for a year with the rank of major. Given command of the Pennsylvania State Regiment, which later became the 13th Pennsylvania Regiment, Stewart led his troops with distinction at Brandywine and Germantown in 1777. He was wounded while leading a detachment at the Battle of Monmouth in the summer of 1778. Despite Stewart's ability to cool tensions during the 1780 mutiny of the Connecticut Line, his regiment later became involved in the Pennsylvania Line Mutiny.
