The sand frog (Heleioporus psammophilus) is a species of frog in the family Myobatrachidae. It is endemic to southwest Western Australia. Its natural habitats are angular fine-grained sandy soil in temperate forests, temperate shrubland, Mediterranean-type shrubby vegetation, shrub-dominated wetlands, swamps, intermittent freshwater lakes, and intermittent freshwater marshes. In southern populations of H. psammophilus the males do not have nuptial spines (northern populations do) so this cannot be relied on as a distinguishing feature from Heleiporus eyrie which does not have nuptial spines in males at all.
It breeds in autumn, males waiting in burrows dug into sandy soils that will flood in winter.
