Vahanga is a small uninhabited atoll part of the Acteon Group in the Tuamotu archipelago, French Polynesia and belongs to the municipality of the Gambier Islands.

It is a low atoll with a landing place on the northwest side of the island near a white house, but there is no access to the lagoon.

The first recorded sighting of this atoll was made during the Spanish expedition of the Portuguese navigator Pedro Fernández de Quirós on 5 February 1606 under the name Las Cuatro Coronadas (the "four crowned" (by coconut palms)),[2][3] however these observations were not fully documented.

As such, the first unambiguous approach to the island was made in 1833 by navigator Thomas Ebrill on his merchant vessel Amphitrite and again in 1837 by Lord Edward Russell, commander of the H.M.S Actaeon, the name given to the group.

[5] Vahanga hosts a flora composed of coconut trees, Portulaca lutea,[6] Cassytha filiformis,[7] and Amaranthaceae such as the species Achyranthes aspera var.
