McArthur Creek is a backcountry campground in Yoho National Park, British Columbia, situated on the Ottertail River where Goodsir, McArthur, and Ottertail creeks converge.

It is the fifth and most remote of Yoho's backcountry campgrounds, distinct from the four campgrounds clustered in the Yoho Valley.

The site serves as a key access point for the Rockwall Trail in Kootenay National Park via Goodsir Pass, making it a popular stop on ambitious multi-day routes through the Canadian Rockies.

It can also be reached via the Ottertail fire road, which is open to both hikers and cyclists. The campground is reservable through Parks Canada.
