Rabih az-Zubayr ibn Fadl Allah or Rabih Fadlallah (Arabic: رابح فضل الله ,رابح الزبير ابن فضل الله), usually known as Rabah in French (c. 1842 – April 22, 1900), was a Sudanese warlord and slave trader who established a powerful empire east of Lake Chad, in today's Chad.

Born around 1842 to an Arabic tribe in Halfaya Al-Muluk, a suburb of Khartoum, he first served with the irregular Egyptian cavalry in the Ethiopian campaign, during which he was wounded. When Rabih left the army in the 1860s, he became the principal lieutenant of the Sudanese slaveholder Sebehr Rahma.
