Fort Whipple, Military museum in Prescott, Arizona, United States.

Fort Whipple Museum occupies a restored 1909 officer's quarters on the grounds of the former military installation near Granite Creek. The building now functions as a museum within the VA Medical Center campus.

The post was set up on December 23, 1863 at Del Rio Springs by Major Edward Banker Willis and Captain Nathaniel J. Pishon with Companies C and F of the First California Volunteers, under General Order #27 of General James Henry Carleton. Governor John Noble Goodwin's party arrived on January 22, 1864 and ran the territorial government from tents and log cabins there. In mid-May 1864 the fort moved twenty-one miles south to Granite Creek, and Prescott became the permanent capital.

The exhibits document how the site evolved from a military outpost to a modern medical facility serving veterans. Visitors can trace this transformation through photographs and artifacts that show how the place's purpose shifted over generations.

The museum occupies a restored 1909 officer's quarters within the VA Medical Center campus. Visitors check in at the security gate with valid photo identification before proceeding to the building.

The Del Rio Springs site, the fort's first location, was later renamed Camp Clark after John A. Clark, Surveyor General of the New Mexico Territory, and was eventually sold and became Postle's Ranch. A plaque there records that Arizona's territorial government operated from tents and log cabins between January 22 and May 18, 1864.
