Diploglottis is a genus of 10 species of trees known to science, constituting part of the plant family Sapindaceae. They grow naturally in rainforests and margins of adjoining humid forests in eastern Australia and New Guinea. Some species are known as native tamarind or small-leaved tamarind; they have no direct relationship with the true tamarind. One Australian species, D. australis is grown as a street tree in the Northern Rivers area of New South Wales, principally Lismore and is known locally as the native tamarind.
