Motoori Haruniwa (本居 春庭, March 17, 1763 - December 13, 1828) was a scholar of Kokugaku, and student of the Japanese language.
Haruniwa followed his father and studied the Japanese language from childhood.
His father, Norinaga made Haruniwa copy literature of antiquity.
He contracted an eye disease from August 1791, eventually going blind in 1795.
His disease is supposed to be an Uveitis by Adachi Kenichi (足立巻一, a student of Haruniwa.).
