Toi (土肥町, Toi-chō) is a town located in Tagata District, Shizuoka Prefecture, Japan on the west coast of Izu Peninsula facing Suruga Bay.

On April 1, 2004, Toi, along with the towns of Amagiyugashima, Nakaizu and Shuzenji (all from Tagata District), was merged to create the city of Izu.

Toi was also home to the Toi gold mine, the second most productive gold mine in Japan after Sado, Niigata.

It was the location of the world's largest flower clock.
