Michael Edward Oliver Lambart, 12th Earl of Cavan, (29 October 1911 – 17 November 1988) was a hereditary peer. He succeeded his father in 1950.

Lord Cavan was educated at Radley College, a public school for boys in Oxfordshire.

He was commanding officer of the Shropshire Yeomanry between 1955 and 1958.

He married Essex Lucy Cholmondeley, daughter of Henry Arthur Cholmondeley and Helen Mary Wrigley, on 10 April 1947.
