Reitoru, or Te Pirehi, is a small atoll of the Tuamotu Archipelago in French Polynesia.

The island is inhabited by a small number of people who live by farming pearls and gathering copra.

The first recorded European who arrived to Reitoru Atoll was French Louis Antoine de Bougainville in 1768.

During the 19th and 20th century, Reitoru was an important center for pearl divers.

In 1903, the atoll was devastated by a cyclone, causing the death of approximately one hundred people.
