ʻAbd al-Rabb (ALA-LC romanization of Arabic: عبد الرب) is a male Muslim given name, and in modern usage, surname.
It is built from the Arabic words ʻabd and al-Rabb.
The name means "servant of the Lord", a Muslim theophoric name.
Thus although the name is written in Arabic with letters corresponding to Abd al-Rab, the usual pronunciation corresponds to Abd ar-Rab.
Alternative transliterations include ‘Abd ar-Rabb, Abdul Rab, and others, all subject to variable spacing and hyphenation.
