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 to negotiate what would become the Treaty of Shimoda. Putyatin's fleet was damaged in a tsunami, following the powerful Ansei-Tōkai earthquake of 23 December 1854. Diana was spun round 42 times on its moorings and was so badly damaged that it sank in a later storm in the bay of (宮島村) (modern Fuji-shi, 富士市), while sailing from Shimoda to Heda for repairs.
