Aceratium is a genus of about 20 species of trees and shrubs of eastern Malesia and Australasia from the family Elaeocarpaceae. ^{[1] [2] [3] [4] [5]} In Australia, they are commonly known as carabeens. ^{[4] [5]} They grow naturally in rainforests, as large shrubs to understorey trees and large trees. ^{[1] [2] [4] [5]}

They grow naturally in New Guinea, the centre of diversity, in New Britain, New Ireland, Vanuatu, Sulawesi, Moluccas, ^[1] and in Australia, where botanists have formally described five species endemic to the Wet Tropics rainforests of northeastern Queensland. ^{[2] [4] [5]}

Some species have uses for their fruits as food and, ^[1] although not yet well known, some have popularity in cultivation, for example in Brisbane.^{[ citation needed ]}
