The Gulf of Gabes, also Cabès, Cabes, Gaps, , also known as Lesser Syrtis (from  Greek   ; Syrtis Minor in Latin), contrasting with the Greater Syrtis in Libya, is a gulf on Tunisia's east coast in the Mediterranean Sea, off North Africa. The gulf roughly spans the coast from Sfax to Djerba. At the head of the gulf is the city of Gabès (Ghannouche) where the tides have a large range of up to 2.1 m at spring tides. Both Gabès and Sfax are major ports on the gulf, supporting sponge and tuna fisheries, with Gabès being the economic and administrative center.
