Laguna Blanca National Park (Spanish: Parque Nacional Laguna Blanca) is a National Park in the west of the province of Neuquén, Argentina, close to the town of Zapala.

The lagoon used to host the largest known subpopulation of the endemic Patagonia frog (Atelognathus patagonicus), but this has been extirpated by introduced predatory fish; the species survives in isolated ponds in the buffer zone of the national park.

[2] Near the lagoon is the Salamanca cave, historically inhabited by humans, where rock paintings, typical of northern Patagonia, can be seen.

The park has an arid and windy climate with a large diurnal range.

[3] Rainfall is low, averaging between 150 and 200 mm (5.9 and 7.9 in) per year, most of it concentrated in winter.
