Ian Derek Francis Ogilvie-Grant, 13th Earl of Seafield (born 1939) is a British peer and landowner.
Ogilvie-Grant is the son of Derek Herbert Studley-Herbert and Nina Ogilvie-Grant, 12th Countess of Seafield. As the head of the Seafield family's 84,500-acre estate, he is one of the principal landowners in Scotland.[1] He was a member of the House of Lords from 1969 until the reforms in 1999 removed most hereditary peers. He was affiliated with the Conservative Party.[2]
Ogilvie-Grant married in October 1960 and had two children, James, also known as Lord Reidhaven, and Alexander. He separated from his wife in August 1969, and the couple were divorced on 24 July 1971.[3]
