Cathedral Provincial Park and Protected Area, Provincial protected area in British Columbia, Canada.

Cathedral Provincial Park and Protected Area covers about 33,000 hectares in the Cascade Range, its western and northern edges formed by the Ashnola River and its eastern edge by Ewart Creek. The park holds the Cathedral Lakes basin, granite peaks such as Cathedral Mountain near the international border, and the small protected area lies to the north. Its southern boundary is the Canada–United States border.

Cathedral Provincial Park was established on May 2, 1968, covering 7,372 hectares in a narrow north–south corridor along Lakeview Creek, including the Cathedral Lakes area. After lengthy consultations with local interest groups, industry and researchers, its boundaries were redrawn to follow natural features, expanding the park to roughly 33,000 hectares. On April 18, 2001, the adjacent 25,889-hectare Snowy Protected Area was established.

The land sits within the traditional territory of the Nlaka'pamux and Syilx peoples, who moved through here seasonally to hunt and gather food. These practices shaped how people understood and lived in this landscape for generations.

The protected area has multiple entry points and offers front-country camping accessible by vehicle in certain locations. Lodging options like Cathedral Lakes Lodge provide accommodations, but no public roads run through the park itself.

The region is home to a mountain goat population numbering between 24 and 28 individuals living in steep alpine terrain. These animals occasionally visit camping areas searching for salt, creating unexpected encounters for visitors who spend time in the high country.
