Lake McDonald Lodge Historic District, Historic district near Lake McDonald, Montana, US.

Lake McDonald Lodge Historic District is a collection of historic buildings at a lake in Montana featuring a three-story stone and wood main building, guest cabins, dormitories, and service structures surrounded by cedar forest. The site sits within Glacier National Park and contains multiple architectural styles from the park's early development period.

The district originated as the Lewis Glacier Hotel, built between 1913 and 1914, and received National Historic Landmark status in 1987 for its architectural importance. The site developed gradually from 1907 onward with original log cabins that represent the park's early settlement period.

The lodge was built as the Lewis Glacier Hotel by John Lewis in 1913–1914, replacing the Snyder Hotel. The log Soda Fountain of 1927 later became a recreation hall for employees, and Snyder Hall, built in 1911 as an assembly hall, was converted into a dormitory.

The lodge stands on the shore of Lake McDonald, with the main building, cabins, dormitories and the General Store grouped along the main road; the 1934 stone bridge over Snyder Creek links the grounds. The Going-to-the-Sun Road provides access, and the area is busiest in summer. The historic core is compact enough to walk, though some structures sit on the hillside behind the lodge.

The district preserves eleven original log cabins from 1907 that stand among the park's oldest remaining structures. A stone bridge crossing Snyder Creek, completed in 1934, connects different areas and shows the building techniques available to early architects of the region.
