The French ironclad Thétis was a wooden-hulled armored corvette built for the French Navy in the late 1860s. She was named for the Greek sea-goddess Thetis. During the Franco-Prussian War she was assigned to a squadron of French ships that attempted to blockade the Prussian ports in the Baltic Sea in 1870. She accidentally rammed her sister Reine Blanche in 1877. En route to the Pacific in 1884 her propeller fell off and she had to return to France under sail. Thétis was eventually hulked in New Caledonia.

The Alma-class ironclads were designed as improved versions of the armored corvette Belliqueuse suitable for foreign deployments. Unlike their predecessor the Alma-class ships were true central battery ironclads as they were fitted with armored transverse bulkheads. Like most ironclads of their era they were equipped with a metal-reinforced ram.

Thétis measured 69.03 meters (226 ft 6 in) between perpendiculars, with a beam of 14.13 meters (46 ft 4 in). She had a mean draft of 6.26 meters (20 ft 6 in) and displaced 3,569 metric tons (3,513 long tons). Her crew numbered 316 officers and men.

The ship had a single horizontal return connecting-rod steam engine driving a single propeller. Her engine was powered by four oval boilers. On sea trials the engine produced 1,676 indicated horsepower (1,250 kW) and the ship reached 11.99 knots (22.21 km/h; 13.80 mph). Unlike all of her sisters except Jeanne d'Arc, she had two funnels, mounted side-by-side.Thétis carried 250 metric tons (250 long tons) of coal which allowed the ship to steam for 1,620 nautical miles (3,000 km; 1,860 mi) at a speed of 10 knots (19 km/h; 12 mph). She was barque-rigged and had a sail area of 1,453 square meters (15,640 sq ft).
