Mori Hiromichi (森 博達, born in 1949) is a Japanese linguist. He makes a study of Chinese phonology and of Old Japanese transcripted with Chinese characters by sound.

He is renowned for a research on Nihonshoki. He divides the history book into two groups and claims that Group α (Vol. 14-21, 24-27, 30) was documented by native speakers of the Northern Chinese dialect during the Tang Dynasty while Group β (Vol. 1-3, 22-23, 28-29) was written by Japanese. He noticed that Group α is standard written Chinese and applies Chinese characters consistently to Japanese words, but Group β is Japanized Chinese and indiscriminates some characters that were distinguished in Northern Chinese.
