Nukutepipi, or Nuku-te-pipi[2] is an atoll in French Polynesia, Pacific Ocean.

Its reef is quite broad, enclosing completely the small lagoon, which has a deep area at its centre.

[3] First sighting recorded by Europeans was by the Spanish expedition of Pedro Fernández de Quirós on 4 February 1606.

With the other three atolls of the Duke of Gloucester Islands they were named Cuatro Coronas (Four Crowns in Spanish).

[4] British naval officer and explorer Philip Carteret visited it on 12 July 1767 who only referred to it in his logs as "the southernmost island".
