Manihi, or Paeua,[3] is a coral atoll in the Tuamotu Archipelago, part of French Polynesia.

The lagoon is well-known among snorkelers for its beautiful and diverse marine fauna, including, among other species, the manta ray.

There are two ancient Polynesian ceremonial platforms constructed of blocks of coral (marae in Tuamotuan) on Manihi.

The first recorded Europeans to arrive to Manihi were Dutch explorers Jacob le Maire and Willem Schouten on their 1615–1616 Pacific journey.

British explorer John Byron, who reached Manihi in June 1765, called the atoll "Prince of Wales Island".
