Mohamed Habib Gherab (8 May 1926 – 17 March 2011) (Arabic: محمد الحبيب غراب) was a United Nations Under Secretary-General, Tunisian diplomat, and senior government official.
Gherab was educated at Sadiki College in Tunis and is a graduate of the Faculty of Law of Paris.
After joining the Neo Destour Party as a young militant for the independence of Tunisia, in 1955 he became a member of the cabinet of Mongi Slim, the Interior Minister in the government of Prime Minister Tahar Ben Ammar as it negotiated the process that led to the effective independence of Tunisia on 20 March 1956.
Gherab later became the only chief of staff to Taieb Mehiri, the first Interior Minister of independent Tunisia during his entire tenure from 1956 until 1965.
As director of personnel, Gherab was accused of appointing un- and under-qualified applicants from Arab countries, discriminating against women in hiring, and hiring men for high-salaried positions where lower-paid female employees did the majority of the work.
