Diana was a frigate of the Imperial Russian Navy. She was built in 1853, and was the flagship of the Russian explorer Yevfimy Putyatin when he visited Japan in 1854. Putyatin's fleet was damaged in a tsunami, following the powerful Ansei-Tōkai earthquake of 23 December 1854. The Diana sank while sailing from Shimoda to Heda for repairs. She sank in the bay of Miyajima-mura (宮島村) (modern Fuji-shi, 富士市).
