Julian Edward Alfred Mond, 3rd Baron Melchett (9 January 1925 – 15 June 1973) was an English industrialist.
Julian Mond was the younger son of Henry Mond, 2nd Baron Melchett and Gwen Wilson. He was educated at Eton and rather than going to university joined the Fleet Air Arm in 1942. Here he served in the Atlantic and on the Russian convoys. His elder brother, Derek, was killed in action in 1945, meaning that on their father's death in 1949, Julian succeeded as Lord Melchett.
After leaving the armed forces, Melchett joined Air Contractors Ltd, a subsidiary of the merchant bank M. Samuel & Co. A year later in 1948, supported by the bank, he founded a farming company based in Norfolk, British Field Products Limited, which specialised in grass-drying and animal feedstuffs. Melchett soon afterwards joined the merchant bankers M. Samuel & Co. This company merged with Philip Hill, Higginson and Erlanger Ltd to form Hill Samuel & Co. Limited and Melchett became director in charge of the banking and overseas departments. He was also a director of the Guardian Assurance Company and of the Anglo-American Shipping Co Ltd. He was an adviser to the British Transport Docks Board, a member of the council of administration of the Malta Dockyard and on the councils of the Confederation of British Industry and the National Economic Development Council.
In 1966 Harold Wilson asked him to be chairman of a committee to plan the nationalization of the British steel industry, and from that time until his death he was effectively the chairman of what became the British Steel Corporation. This was formed from fourteen major iron and steel companies and other smaller ones who together employed more than a quarter of a million workers.
