Khalid Hassan Abbas (Arabic: خالد حسن عباس; March 17, 1936 – August 20, 2015) was a Sudanese general and politician.

Abbas rose to prominence as a result of his involvement in the 1969 Sudanese coup d'état, following which he became the Deputy Chairman of the ruling National Revolutionary Command Council.Abbas was appointed as Minister of Defense on 29 October 1969[1] following a cabinet reshuffle implemented to strengthen the army's control over the Sudanese government.

As Defense Minister he, alongside Babiker, would push Nimeiry to adopt a more aggressive response to the rising threat to the government posed by the Ansar movement, resulting in the brutal crackdown seen on Aba Island in 1970.

[2] Abbas's tenure also saw the attempted 1971 Sudanese coup d'état, during which his younger brother was killed.

The RCC was disbanded following the 1971 coup attempt at Abbas's insistence, and Nimeiry instead assumed the title of President in September 1971.
