Fujiwara no Nakanari (藤原 仲成, 764[1] – October 16, 810) was a Japanese noble of the early Heian period.
In 809 he was appointed as kansatsu-shi (観察使) of the Hokurikudō, a position roughly equivalent to sangi, thus joining the ranks of the kugyō.
Later that year, Heizei abdicated the throne in favor of his younger brother Emperor Saga.
However, when Heizei ordered the return of the capital to Heijō-kyō that autumn, relations between the two courts worsened even further, and a few days later Nakanari was captured by Saga's side.
He was confined and demoted to provisional governor of Sado Province, and the next day was executed by the archery of Ki no Kiyonari (紀清成) and Sumiyoshi no Toyotsugu (住吉豊継).
