The Montgomeryshire Militia, later the Royal Montgomeryshire Rifles, was an auxiliary regiment reorganised in the Welsh county of Montgomeryshire during the 18th Century from earlier precursor units. Primarily intended for home defence, it served in Great Britain and Ireland during Britain's major wars. It later became part of the South Wales Borderers until it was disbanded in 1908.
