Thruston's Additional Continental Regiment was an American infantry unit that served for a little more than two years in the Continental Army during the American Revolutionary War. Authorized in March 1777, four companies were organized in Virginia during the spring and summer of 1777. George Washington appointed influential Shenandoah Valley political leader Charles Mynn Thruston as colonel in command. The regiment participated in the Philadelphia Campaign in late 1777. One company was detached from the regiment on 4 April 1778 and became part of Hartley's Additional Continental Regiment. The unit was present in the Monmouth Campaign in June 1778. What was left of the regiment was attached to Grayson's Additional Continental Regiment on 15 November 1778. Grayson's and Thruston's Regiments
