The Gulf of Gabes, called Minor Syrtis in ancient times, is a gulf on Tunisia's east coast in the Mediterranean Sea.

The gulf is 100 kilometers long and wide, with the Kerkena Islands on the northeast and Djerba Island on the southeast. It has a large tidal range, 2.5 meters at spring tides. The city of Gabès is located in the gulf, which is an economic and administrative center. Gabès and Sfax, another major port on the gulf, have sponge and tuna fisheries.
