Rosemary Inn is a historic resort located at Barnes Point, on south shore of Lake Crescent, about 17.2 miles (27.7 km) southwest of Port Angeles, in Olympic National Park.

[2][a] The main property of the district is the Rosemary inn lodge, a big frame structure located to the south of the meadow built by John Daum and opened in 1914 by Rose E. Littleton.

Twelve guest log and wood-frame cabins, each one unique in design, and several other outbuildings, built between the 1920s and the 1930s, occupy the area north of the lodge.

In 1946 the dedication of Olympic National Park was conducted at the lodge at Rosemary Inn.

From 1988, Rosemary Inn was operated by Olympic Park Institute, as an environmental education center.
