Fukutoku-Okanoba (福徳岡ノ場) is a submarine volcano that is part of the Volcano Islands in the Bonin Islands of Japan. It is located 5 kilometers northeast of the island of South Iwo Jima.

The earliest recorded eruption of Fukutoku-Okanoba in 1904 formed an ephemeral island named Shin-Iwo-jima (New Sulfur Island). Other ephemeral islands have also formed, the most recent of which formed in 1986. The most recent eruption of Fukutoku-Okanoba was in 2010, when the Japanese coast guard spotted steam rising one kilometer above the ocean and water discoloration of the surrounding area.
