Michael Beaumont 22nd Seigneur of Sark
 John Michael Beaumont OBE (born 20 December 1927) is the 22nd and presently reigning seigneur of Sark. He worked as a civil engineer before succeeding his paternal grandmother Sibyl Hathaway in 1974. During his rule Beaumont saw the loss of many feudal rights enjoyed by the seigneurs. He is consequently often described as the last feudal baron.
