Moriyama Einosuke (森山 栄之助, July 10, 1820 – May 4, 1872) was a samurai during the Tokugawa shogunate, and an interpreter of Dutch and English.

He was called upon to assist shogunate officials during the "Manhattan Incident" of 1845, during which the American whaling ship Manhattan approached Edo to repatriate 22 castaway Japanese seamen.

Samuel Wells Williams, a member of Perry's second visit noted in 1854: A new and superior interpreter came with Saborosuke, named Moriyama Yenosuke ...

He speaks English well enough to render any other interpreter unnecessary, and this will assist our intercourse greatly.
