Fort Washakie, Former U.S. Army fort and historic district in Fremont County, Wyoming, US

Fort Washakie is a historic settlement center within the Wind River Indian Reservation that today primarily serves as the seat of tribal government administration. The area contains various administrative buildings and community facilities located along the main route through the reservation.

Established in 1869 as Camp Augur, named for General Christopher C. Augur of the Department of the Platte, the post became Camp Brown in 1870 for Captain Frederick H. Brown, killed at the Fetterman Fight in 1866. In 1878 it was renamed Fort Washakie for Shoshone Chief Washakie. It stayed a military outpost until 1909, when commander William A. McCain decommissioned it and transferred it to the Shoshone Indian Agency.

The fort is named after Chief Washakie of the Shoshone, the leader whose name it took in 1878. Washakie's grave lies on the grounds, as does that of Sacajawea, the guide of the Lewis and Clark Expedition. The site sits within the present-day Wind River Indian Reservation.

The stone building with the "FORT WASHAKIE" sign faces the road, with a concrete sidewalk along its front. The graves of Chief Washakie and Sacajawea lie on the fort grounds, within the Wind River Indian Reservation. The post was decommissioned in 1909 and transferred to the Shoshone Indian Agency.

The fort grounds hold the graves of Chief Washakie and Sacajawea, the Shoshone woman who guided the Lewis and Clark Expedition. Both burials lie within the Wind River Indian Reservation.
