Koga Kin'ichirô was a Confucian scholar in service to the Tokugawa shogunate. He is known for his translation work and involvement otherwise in activities related to the shogunate's engagement with Western powers in the 1850s, including being one of the signers of the 1854 Treaty of Shimoda (along with Tsutsui Masanori and Kawaji Toshiakira).

In 1855, he was named ni-no-maru rusi and kashiradori of the shogunate's Institute of Western Studies (Yôgakusho). He also served briefly as Osaka machi bugyô, for about one month, in 1864.

His students included Hirata Tôsuke.
