Tun Musa bin Hitam (Jawi: موسى بن هيتم; born 18 April 1934) is a Malaysian politician who was Deputy Prime Minister of Malaysia from 1981 to 1986, serving under Mahathir Mohamad. He was the chairman of Sime Darby Berhad. Early life and education Musa bin Hitam was born in Johor Bahru, British Malaya in 1934. Musa was born to a Malay father of Javanese descent and a mother of Chinese descent, who was adopted by and grew up in a Malay household at the age of five. He continued his studies at the English College Johore Bahru. He also received his bachelor's degree from the University of Malaya and his master's degree from the University of Sussex.
