Mount Tujuh is a caldera volcano in the Barisan Mountains, in Kerinci Seblat National Park, Jambi province, a few kilometres east of Mount Kerinci. Its highest peak on the caldera rim reaches 2,732 m, and the crater holds the deep-blue Lake Gunung Tujuh at 1,996 m. The climb ends at the crater rim at 2,010 m, beside the lake's outflow.

The name Tujuh means "seven" in Indonesian, referring to the seven peaks along the caldera rim. The crater lake, Danau Gunung Tujuh, lies at 1,996 m and remains largely untouched by human activity. The endangered pitcher plant Nepenthes aristolochioides is endemic to the mountain's high altitudes.

The best climbing season is from June to September when weather conditions are most stable and predictable. Visitors should allow adequate time for acclimatization and bring sturdy footwear, rain gear, and sufficient water for the ascent.

Only three of Mount Tujuh's seven peaks have ever been climbed. The mountain also supports one of just three known wild populations of the tropical pitcher plant Nepenthes aristolochioides, which grows in its highlands.
