Aigüestortes i Estany de Sant Maurici National Park (Catalan: Parc Nacional d'Aigüestortes i Estany de Sant Maurici, Spanish: Parque Nacional de Aiguestortes y el Lago San Mauricio) is one of the fourteen Spanish National Parks, the second in the Pyrenees and the only one in Catalonia.
A wild mountain region in the Pyrenees, with peaks rising to 3,017 m (Besiberri Sud) and with nearly 200 lakes, many of them of glacial origin, the park comprises a core area of 141 km² and a buffer zone of 267 km² surrounding the park.
The park has an elevation range from 1,600 to 3,000 metres and contains four major vegetation zones: lower montane, upper montane, subalpine and alpine. It has a great variety of alpine vegetation, including dark-coniferous mountain forest (fir, mountain pine) and subalpine pine forest.
The fauna includes Pyrenean chamois, marmot, ermine, roe deer, among other mammals and numerous birds (Black Woodpecker, Common Crossbill, Lammergeier, Golden Eagle).
