Nawab Khair Bakhsh Marri (28 February 1928 – 10 June 2014), Balochi: نواب خیر بخش مری) was a Pakistani politician from the province of Balochistan in Pakistan.

Only when oil and gas exploration started in the Marri tribal areas during General Ayub Khan's regime in Pakistan, his tribal nationalist feelings and political consciousness were aroused.

[3] Marri became a member of the National Assembly of Pakistan, after winning a seat from Balochistan in the Pakistani general election, 1970.

Due to the steps taken by the federal government to suppress the rebellion by Zulfiqar Ali Bhutto regime in the 1970s, Marri spent many years in exile in Afghanistan, and only returned to Pakistan when the USSR-backed government of Mohammad Najibullah supporting him in that country, had fallen in the early 1990s.

He was admitted to Liaquat National Hospital, Karachi in a critical condition on 6 June 2014 and had been under treatment there.
