Yevfimiy Vasilyevich Putyatin, also known as Euphimius Putiatin, was an admiral in the Imperial Russian Navy. His diplomatic mission to Japan resulted in the signing of the Treaty of Shimoda in 1855, for which he was made a count. His mission to China in 1858 resulted in the Russian Treaty of Tianjin.

The Treaty of Shimoda of February 7, 1855, was the first treaty between the Russian Empire, and the Empire of Japan, then under the administration of the Tokugawa shogunate. Following shortly after the Convention of Kanagawa signed between Japan and the United States, it effectively meant the end of Japan's 220-year-old policy of national seclusion (sakoku), by opening the ports of Nagasaki, Shimoda and Hakodate to Russian vessels and established the position of Russian consuls in Japan and defined the borders between Japan and Russia.
