Ōtomo no Kuronushi (大友 黒主) was a Japanese poet, one of the Rokkasen, the "Six Poetic Geniuses" described in the Kokin Wakashū, a classical poetic anthology.
His poems suggest strong influence from his close ties with the lands of Ōmi and Shiga.
According to the "Mumyosho", collected articles on poetics authored by Kamo-no-Chomei, Kuronushi ascended to the status of a god and was enshrined as a "Myojin" god in the Shiga Province of Ōmi.
In one account, he is the same person as Otomo-no-Suguri-Kuronushi who was mentioned in the ministerial bulletin of 866 (Jogan 8).
Ōtomo-no-Suguri is a clan seated at Ōtomo Village in the Shiga Province of the Ōmi Domain.
