Dismal Nitch is the name of a cove along the lower Columbia River in Washington state, notable as the Lewis and Clark Expedition's last campsite before sighting the Pacific Ocean.
Today the area has a rest stop on the Washington State Route 401 highway just east of the Astoria–Megler Bridge, with a short trail to a 2009 monument. The rest area and monument are officially part of Lewis and Clark National Historical Park.
