Vaccinium reticulatum, known as ʻōhelo ʻai in Hawaiian, is a species of flowering plant in the heather family, Ericaceae, that is endemic to Hawaii.

It grows at altitudes of 640–3,700 m (2,100–12,140 ft) on lava flows and freshly disturbed volcanic ash on Maui and Hawaiʻi, and less commonly on Kauaʻi, Oʻahu, and Molokaʻi.

Adaptations to volcanic activity include the ability to survive ash falls of over 25 cm (9.8 in) depth.

The fruit is an edible berry 8–14 mm (0.31–0.55 in) diameter, ranging in color from blue to purple to red to orange to yellow.

They are an important food source for the nēnē (Branta sandvicensis); the seeds are dispersed in the birds' droppings (endozoochory).
