Ali Nasir Muhammad Husani () (born 31 December 1939, Mudiyah, Mutawakkilite Kingdom of Yemen) is the former leader of South Yemen serving as General Secretary of the Yemeni Socialist Party between 1980 and 1986. He was twice president of South Yemen and once the Prime Minister. He served as the Prime Minister from 2 August 1971 until 14 February 1985 and as Chairman of the Presidential Council from 26 June 1978 - 27 December 1978. In April 1980, South Yemeni president Abdul Fattah Ismail resigned and moved to Moscow. His successor was Ali Nasir Muhammad who took a less interventionist stance toward both North Yemen and neighbouring Oman. On January 13, 1986, a violent struggle began in Aden between Ali Nasir's supporters and supporters of the returned Ismail. (See South Yemen Civil War) Fighting lasted for more than a month and resulted in thousands of casualties, Ali Nasir's ouster, and Ismail's death. Muhammad's term had lasted from 21 April 1980 to 24 January 1986. Some 60,000 people, including the deposed Ali Nasir, fled to North Yemen. He was succeeded by Haidar Abu Bakr al-Attas.
