Nachi (那智) was the second vessel completed of the four-member Myōkō class of heavy cruisers of the Imperial Japanese Navy (IJN), which were active in World War II. The other ships of the class were Myōkō, Ashigara, and Haguro. She was named after a mountain in Wakayama Prefecture.

The Myōkō-class cruisers were a series of four heavy cruisers built for the Imperial Japanese Navy in the late 1920s. Three were lost during World War II.
