Robert James Byron, 13th Baron Byron (born 5 April 1950), is a British nobleman, peer, politician, and barrister. He is a descendant of a cousin of Romantic poet and writer George Gordon Byron, 6th Baron Byron.

Byron is the son of Lt. Col. Richard Geoffrey Gordon Byron, 12th Baron Byron, and Dorigen Margaret Esdaile. He was educated at Wellington College in Berkshire and studied law at Trinity College, Cambridge.

He married Robyn Margaret McLean in 1979. She became Lady Byron when her husband inherited the barony on 15 June 1989. The couple have four children:

• The Hon. Caroline Anne Victoria Byron (1981)
• The Hon. Emily Clare Byron (1984)
• The Hon. Sophie Georgina Byron (1986)
• The Hon. Charles Richard Gordon Byron (28 July 1990); heir apparent.^[1]

Byron was admitted to the Inner Temple in 1974 and thus became entitled to practise as a barrister. He eventually became a partner at Holman, Fenwick & Willan, and a President of the British Byron Society.

Upon inheriting his title, Byron became entitled to sit in the House of Lords, where he took the Oath of Allegiance in October 1989. He attended chamber debates infrequently, speaking mostly on bills related to the justice system and shipping law. Along with most hereditary peers, he lost the right to attend when the House of Lords Act 1999 took effect in November 1999.^[2]
