Sakai Hideyuki (坂井 秀至, born April 23, 1973) is a Japanese 8 dan professional. He is currently a top professional in Japan, but is also notable for having had a long amateur career before qualifying as a professional. He was one of the first to be awarded an amateur 8-dan diploma. In 2000 he won the World Amateur Go Championship, and was accepted as a professional by the Kansai Ki-in in the following year. As part of the qualification procedure, he played four testing games against professionals and won them all. He was immediately awarded a 5 dan professional rank at the age of 28.

Prior to becoming pro, he was a medical junior resident.

In 2019, Sakai decided to resume his medical career; he announced he was taking an unlimited leave of absence from all tournaments.
