SMS Hansa was a protected cruiser of the Victoria Louise-class cruiser, built for the German Imperial Navy in the 1890s, along with her sister ships Victoria Louise, Hertha, Vineta, and Freya. Hansa was laid down at the AG Vulcan shipyard in Stettin in 1896, launched in March 1898, and commissioned into the Navy in April 1899. The ship was armed with a battery of two 21 cm guns and eight 15 cm guns and had a top speed of 19 knots.

Protected cruisers, a type of cruising warship of the late-19th century, gained their description because an armoured deck offered protection for vital machine-spaces from fragments caused by shells exploding above them. Protected cruisers resembled armored cruisers, which had in addition a belt of armour along the sides.
