Roger de Montgomerie (died 1094), also known as Roger the Great de Montgomery, was the first Earl of Shrewsbury. His father was Roger de Montgomery, seigneur of Montgomery, and was a relative, probably a grandnephew, of the Duchess Gunnor, wife of Duke Richard I of Normandy. The elder Roger had large holdings in central Normandy, chiefly in the valley of the Dives, which the younger Roger inherited.
