Ranunculus acraeus is a species of flowering plant in the buttercup family, Ranunculaceae, found in New Zealand. This rare and native species strictly grows on an alpine habitat, hence the name acraeus, meaning "on high". The plant grows about 50 cm (20 in) in width, and is covered in beautiful, bright yellow flowers. It may be mistaken for R. piliferus but research has shown R. acraeus to be its own distinctive species.
Ranunculus acraeus is endemic, therefore it is isolated to a specific geographic location. It is found only in South Island, North Otago, New Zealand - more specifically, Barrier Range, St Marys Range, St Bathans Range, Kakanui Mountains, Ida Range, and the Waitaki Valley regions of South Island, North Otago. It is also found in Hall Range and Godley River valley regions of southwest Canterbury. It occurs in small, scattered subpopulations. The largest population of about 200 plants has been found on Mount St. Mary in St. Mary's Range. The smallest population of about three to four plants has been found on mountains around the Ohau skifield and near Tekapo.
