The Honourable Sir Humphrey Maud KCMG (17 April 1934 – 10 November 2013) was a British diplomat.
Humphrey Maud was the son of the civil servant and diplomat John Redcliffe-Maud, Baron Redcliffe-Maud and his wife, the pianist Jean Hamilton. He attended Eton College, where he was a favourite of Benjamin Britten - Britten dedicated The Young Person's Guide to the Orchestra to Humphrey and his siblings - though Humphrey's father eventually intervened to stop him spending so much time with Britten during the holidays.
Maud studied classics and history at King's College, Cambridge. After a year teaching classics at the University of Minnesota, he entered the Foreign Service in 1959.
Maud was the British Ambassador to Luxembourg from 1982-85, and the British Ambassador to Argentina from 1990-93. In 1993 he became Commonwealth Deputy Secretary-General with responsibility for economic and social affairs, holding the post until he retired in 1999.
