Pukarua, sometimes also listed as "Pukaruha" (especially on French maps), is a coral atoll in the eastern Tuamotu Archipelago. The nearest atoll, Reao, is located 48 km to the ESE.

Pukarua Atoll is 17 km long and its maximum width is 4.5 km. It has a long island on its northeastern reef, shaped somewhat like a fish hook, as well as a number of small islands. The atoll is surrounded by a coral reef without a proper passage. There is a pier from which small to medium-sized ships can be launched.
