Danan (uncertain derivation) was one of the three volcanic cones (the others being Perboewatan and Rakata) on the island of Krakatoa, in the Sunda Strait, in Indonesia. It stood , lay in the central area of the island, and may have been a twin volcano. Danan was almost entirely destroyed in the 1883 eruption of Krakatoa; only a rocky islet named Bootsmansrots remains of it.
