Bab Sidi Abdallah Cherif () was one of the gates of the medina of Tunis, the capital of Tunisia. It was situated at the south-western extremity of the kasbah, but has been destroyed.
It was also called Bab El Ghedar () which means "Gate of the treason".
This gate takes its name from a saint, Sidi Abdallah Cherif, whose tomb is nearby, outside the medina of Tunis's rampart.
