Tatsunosuke Hori

 was a Japanese interpreter and translator of Dutch and English during the Edo period. Although he initially came from a line of Dutch translators, he was later able to learn English.
He was the translator of Commodore James Biddle's 1846 letter at Uraga Channel. He was also present at Commodore Perry's arrival at Uraga on July 8, 1853, and served as an official interpreter. He told Perry in English "I can speak Dutch" and later began a conversation in Dutch with Anton L. C. Portman who could speak Dutch on Perry's ship. He was able to convince the Americans to allow he and Nakajima Saburōsuke (1821–1869), an officer of the Uraga magistracy, to board the USS Susquehanna, on which they delivered the order that all foreign ships were to be expelled from Japanese ports.
He later went on to found an English-teaching school and published a manual on learning English.
