The Royal Manx Fencibles were a body of Manx troops forming part of the British regular army, raised during the wars with France between 1779 and 1810. Initially consisting of three companies for Island defence only, the force was expanded to a full regiment of ten companies in 1795, serving in Ireland during the 1798 Rebellion and at Omagh and Whitehaven before being disbanded at the Peace of Amiens in 1802 and re-embodied in 1803.
