Nakachi Pekumi Kijin (仲地 親雲上 紀仁, 3 February 1789 – 7 April 1859) was a scholar-bureaucrat, physician and surgeon of the Ryūkyū Kingdom.
Nakachi was born in a physician's family; both his father and grandfather were surgeons.
Three years later, he decided to go home, but was caught in a storm midway there and later drifted into the Satsuma Domain.
He studied cowpox vaccination from Bernard Jean Bettelheim, the first Christian missionary to Ryukyu, in 1846.
He received rewards from the king, Shō Iku, and was appointed "imperial physician" (御医者).
