Stelvio National Park (Italian: Parco nazionale dello Stelvio; German: Nationalpark Stilfser Joch) is a national park in northeast Italy. It was created in 1935.

The park is the fourth largest in Italy and covers parts of two regions: Trentino-Alto Adige/Südtirol and Lombardia. It includes land in 24 different towns.

Stelvio National Park shares borders with the Swiss National Park, Adamello Brenta Natural Park, and Adamello Regional Park (Italian: Parco regionale dell'Adamello). Together, these parks cover 400,000 hectares (1,500 square miles) of protected natural areas. The park includes valleys and high mountains, with elevations ranging from 650 meters (2,130 feet) to 3,905 meters (12,812 feet).

In December 2025, a wildlife photographer found about 20,000 dinosaur footprints in the park near the Swiss border. The footprints are about 210 million years old. This site is one of the largest Triassic trace fossil locations discovered. The fossil trackway shows evidence of long-necked, two-legged herbivores preserved on high Alpine cliffs. Scientists consider this a significant paleontological discovery.
