Sfax was a protected cruiser built for the French Navy in the 1880s. She was the first vessel of the type to be built for the French Navy, which was a development from earlier unprotected cruisers like Milan. Unlike the earlier vessels, Sfax carried an armor deck that covered her propulsion machinery and ammunition magazines. Intended to be used as a commerce raider in the event of war with Great Britain, Sfax was rigged as a barque to supplement her engines on long voyages abroad. She was armed with a main battery of six 164 mm (6.5 in) guns and a variety of lighter weapons.
