Camp McGarry was a U.S. military camp located in what is now the Summit Lake Indian Reservation in Humboldt County, Nevada.

It was named for Brevet Brigadier General Edward McGarry.

With a size of 75 sq mi (190 km2) it was, at the time, the largest military reserve in Nevada.

In 1866 the headquarters of the district of Nevada were moved from Fort Churchill to Camp McGarry.

On March 25, 1871, the camp was relinquished by the Army and turned over to the U.S. Department of the Interior for use as the Summit Lake Indian Reservation.
