Ii Naotaka (井伊 直孝, March 16, 1590 – August 16, 1659) was a Japanese daimyō of the early Edo period who served under the Tokugawa shogunate.

Naotaka served in the Siege of Osaka in his brother Naokatsu's stead, where he would gain tremendous favor for his exploits at Tennōji.

Both Naotaka and his father Naomasa are playable characters from the Eastern Army in the original Kessen.

Hikonyan, mascot of Hikone Castle, is based on a folktale about how Naotaka was saved from a lightning strike by a maneki-neko.

[1][2][3] In 1917, Naotaka was posthumously granted the courtesy title of junior third rank (ju san-mi, 従三位) by Emperor Taishō.
