Aukena is the 5th largest of the Gambier Islands in French Polynesia.

Aukena is located about halfway between Mangareva and Akamaru, or about 5 km southeast of Mangareva, which is the largest island of the whole Gambier Islands archipelago.

Aukena is approximately 2.5 km long and about 0.5 km wide, with a total area of 1.35 km2.

Mangarevan oral tradition first mentions the island in the fourteenth century, and archeological excavations show that it has been inhabited since that time.
