Elattostachys is a genus of about 21 species of trees known to science, constituting part of the plant family Sapindaceae.

They grow naturally in the New Guinea, the Moluccas, Sulawesi, Indonesia, Timor, Australia, New Caledonia, Vanuatu, Fiji, Samoa, Niue, Tonga, Palau (Caroline Islands) and the Philippines.

The known centre of diversity of New Guinea has nine known species recognised by science as of 2013.

In Australia, they grow naturally through the northern half of the eastern coastal zone, northwards from the Newcastle region in New South Wales through eastern Queensland to the northernmost point of Australia Cape York Peninsula. One of them E. xylocarpa has a common name of white tamarind, while another E. nervosa has a common name of beetroot tree. A few members of the Australian Sapindaceae are called tamarinds, although they have no close relation to the true tamarind, which is a member of the bean family.
