Mohotani (sometimes spelt Moho Tani; also called Molopu or Motane) is an uninhabited island southeast of Hiva Oa and east of Tahuata in the southern Marquesas Islands. It has an area of 15 km². Much of the island's sparse vegetation has been destroyed by feral goats and sheep, to the extent that following its rare rains, the sea around it is stained red from runoff. Early reports describes the island as fertile, with forest and fields.
