Eugenia reinwardtiana is a shrub to small tree in the family Myrtaceae. Native to tropical forests in Indonesia,^[3] the Australian state of Queensland, and many Pacific Islands, its common names include Cedar Bay cherry, beach cherry, Australian beach cherry, mountain stopper,^[4] nīoi (Hawaiian),^[5] and a'abang (Chamorro). They are typically 2 to 6 m (6.6 to 19.7 ft) in height.^[6]

The tree is particularly common around the Cedar Bay National Park in northern Australia and the edible fruit was especially popular with the hippies who lived there in the 1970s.^{[citation needed]}

The fruits are green at first, then ripen to a bright orange-red colour with a sweet taste and soft flesh.

The tree is cultivated to a limited extent for its edible sweetish fruit that is often eaten out-of-hand, used to flavour drinks and candies, or as a preserve. The fruit is a source of antioxidants.^[7]

The tree is well-suited to amenity horticulture in the tropics, and is grown in the median strips in Cairns.^{[citation needed]} It is readily propagated from fresh seed.^[6]

This species is susceptible to myrtle rust (Austropuccinia psidii).
