Marc Hideo Miyake (三宅 英雄, Miyake Hideo, born July 28, 1971) is an American linguist who specializes in historical linguistics, particularly the study of Old Japanese and Tangut.

Miyake was born in Aiea, Hawaii in 1971, and attended Punahou School in Honolulu, graduating in 1989. He studied Japanese language and literature at University of California, Berkeley, and then studied linguistics at the University of Hawaii at Manoa, from where he obtained his doctorate in 1999, with a dissertation entitled The Phonology of Eighth-Century Japanese Revisited: Another Reconstruction Based upon Written Records.^[1][2] He is best known for his work on the phonetic reconstruction of Old Japanese, but is also known for his work on the extinct Tangut language.
