Allosyncarpia ternata, commonly known as an-binik, is a species of rainforest trees constituting part of the botanical family Myrtaceae and included in the eucalypts group.

They grow naturally into large, spreading, shady trees, and are endemic to the Northern Territory of Australia.

[1][2] The common name anbinik comes from the Kundedjnjenghmi and Kundjeyhmi dialects of Bininj Kunwok, spoken in West Arnhem Land.

[3] The tree dominates the closed monsoon rainforest communities along the sandstone escarpment of the western Arnhem Land Plateau.

[4][5][6][7][8] [2] A species of sandstone favouring monitor, the long-tailed Varanus glebopalma, is closely associated with Allosyncarpia woodland in some parts of its range.
