Mount Amagi (天城山, Amagi-san) is a range of volcanic mountains in central Izu Peninsula in Shizuoka Prefecture, Japan, forming the border between Izu City and Higashi-Izu Town.

Flora in the area include rhododendrons, Japanese andromeda, stewartia monadelpha and Siebold's beech.

Many ships of the Imperial Japanese Navy were named after it, including a corvette, a battlecruiser and an aircraft carrier.

Amagi is listed as one of the 100 Famous Japanese Mountains in a book composed in 1964 by mountaineer/author Kyūya Fukada.
