The Rock Fort Campsite is a natural fortification on the south shore of the Columbia River in The Dalles, Oregon, United States. The Lewis and Clark Expedition camped at this defensible spot for three nights in late October 1805, just after it passed Celilo Falls on its descent to the Pacific Ocean, and again for one night on their return journey. It was here that the expedition first made significant contact and commerce with the Chinookan-speaking peoples of the lower Columbia.{{citation | last1 = Seufert | first1 = Gladys | last2 = Potter | first2 = Elisabeth Walton | last3 = Chuinard | first3 = E. G. | title = National Register of Historic Places Inventory — Nomination Form: Rock Fort Campsite | date = October 1979 | url = {{NRHP url|id=80003389}} | format = PDF}}.{{Citation | last1 = Ambrose | first1 = Stephen E. | authorlink1 = Stephen Ambrose | title = Undaunted Courage: Meriwether Lewis, Thomas Jefferson, and the Opening of the American West | year = 1996 | publisher = Simon & Schuster | location = New York | isbn = 978-0-684-82697-4 | pages = [https://archive.org/details/undauntedcourage00ambr/page/305 305–307] }}
