Abdirizak Haji Hussein (Somali: Cabdirasaaq Xaaji Xuseen; born 1924) in the Galkayo, Mudug Region of Somalia, was Prime Minister of Somalia from 14 June 1964 to 15 July 1967 when the country was controlled by the Somali Youth League (SYL).

In May 6, 2001, an effort by the Transitional National Government (TNG) to create a 25-member working body, dubbed the National Commission for Reconciliation and Property Settlement (NCRPS), was damaged when Abdirizak Haji Hussein was named as its head. The Somalia Reconciliation and Restoration Council (SRRC) and Puntland leadership objected strongly. Hussein later resigned on July 25, 2001.
