Bird Woman Falls, Waterfall in Glacier National Park, United States.

Bird Woman Falls is a waterfall in Glacier National Park that descends in two major cascades. The water originates from snowfields and glaciers on the slopes of Mount Oberlin.

Bird Woman Falls lies just west of the Continental Divide, the drainage boundary that splits Glacier National Park's waters between the Pacific and the Atlantic. The falls are fed by snowfields and a remnant glacier on the north and west flanks of Mount Oberlin, and the Going-to-the-Sun Road, which crosses the park east to west, passes within about two miles of the cascade.

The falls take their name from Bird Woman, the Shoshone guide Sacagawea, who travelled with the Lewis and Clark expedition in 1805–1806. The name ties the waterfall to that exploration story rather than to a local tribal tradition recorded at the site.

The best place to view the waterfall is from designated pullouts along Going-to-the-Sun Road. The falls can be seen throughout the year, though water volume changes with the seasons.

Bird Woman Falls is fed by snowfields and a remnant glacier on the north and west flanks of Mount Oberlin, and its flow has been known to almost cease in autumn. The falls are visible from about two miles (3.2 km) away along Going-to-the-Sun Road.
