Geocrinia alba, commonly known as the white-bellied frog, is a small frog in the family Myobatrachidae. It occupies an area near Margaret River in swampy depressions adjoining creeks. Threats from altered ecology have made this a critically endangered species of south-western Australia.
G. alba is very similar in appearance to Geocrinia vitellina (the Orange-bellied frog); having spots of dark brown on a light brown or grey back and a snout-vent length of 17–24 mm. The underparts, however, are white. It is part of the Geocrinia rosea frog complex.
