Diploglottis harpullioides, commonly known as Babinda tamarind, is a rainforest tree in the lychee and maple family Sapindaceae which is found only in northeast Queensland, Australia.

The compound leaves may reach 58 cm (23 in) in length (including the petiole), and have between 4 and 8 stiff, hairless leaflets arranged in opposite pairs.

[4]: 392 [5][6][7] The Babinda tamarind was first described by the Australian botanist Sally T. Reynolds in the first of a series of papers on the Sapindaceae species in Australia.

This paper, titled "Notes on Sapindaceae in Australia, I" was published in 1981 in Austrobaileya, the official journal of the Queensland Herbarium.

[7] This species is endemic to northeastern Queensland, and occurs in coastal flats and adjacent ranges from near Rossville and Cedar Bay in the Ngalba Bulal National Park, south to about Innisfail, and from sea level to about 400 m (1,300 ft).
