Nukutavake or Nukutuvake is an island in the Tuamotu group in French Polynesia. It lies 1,125 kilometres (699 mi) from Tahiti. The closest land is small Pinaki Atoll, located 15 kilometres (9.3 mi) to the southeast. Vairaatea Atoll lies 38 kilometres (24 mi) to the west of Nukutavake.
Nukutavake's length is 5 kilometres (3.1 mi) and its width between 0.45 kilometres (0.28 mi) and 1.3 kilometres (0.81 mi). Nukutuvake is not a typical Tuamotu atoll, but a single island. It was formed when its lagoon filled up with silt, in a similar manner as Fua Mulaku in the Maldives, which has a similar size and shape. There are shallow remains of the lagoon filled with marshy vegetation. The higher ground has many coconut palms.
Nukutavake has 139 inhabitants; Tavananui is the largest town. Many islanders have left the island in recent years, mainly to Tahiti, in search for work. There are a number of abandoned houses on the island. The people who remain live primarily on fish and copra production. There is a cyclone shelter on Nukutavake
