Weippe Prairie, National Historic Landmark Prairie in Clearwater County, Idaho.

Weippe Prairie is a roughly two-by-three-mile upland clearing at about 3,000 feet in Clearwater County, Idaho, just north of the Middle Fork Clearwater River near the town of Weippe. The open field, bordered by farmland cleared from pine forest, is known for its camas flowers. It lies within Nez Perce National Historical Park.

In fall 1805, the Lewis and Clark Expedition arrived at this highland after crossing the Bitterroot Mountains, making their first encounter with the Nez Perce people. This meeting proved decisive in shaping the rest of their westward journey.

The name Weippe comes from a Nez Perce word reported to mean "very old place" or to refer to a spring or the camas grounds; no literal translation has been found. The prairie's camas fields drew Nez Perce gatherers, and the roots, eaten as camas root cakes, were a staple of their diet.

The prairie lies just north of the Middle Fork Clearwater River at about 3,000 feet, beside the town of Weippe in Clearwater County. The camas-covered landmark parcel is reached from Weippe; the surrounding fields and pine stands are private farmland and forest, so stay on public ground. The Nez Perce National Historical Park interprets the site.
