Mowbray Henry Gordon Howard, 6th Earl of Effingham (29 November 1905 – 22 February 1996), styled Lord Howard from 1927 to 1946, was a British peer. He was born on 29 November 1905 to Gordon Howard, 5th Earl of Effingham, and Rosamond Margaret Hudson. He was educated at Lancing College. In October 1932, Howard was charged with manslaughter after an inquest found that he had knocked down an agricultural labourer in his car. However, the case was dismissed when it came to the magistrates' court at Maidenhead.
