U.S. Army Supply Base New Orleans, Military supply depot in New Orleans, United States

The U.S. Army Supply Base New Orleans is a former military supply depot whose nine contributing resources include three original warehouses used for military supplies and munitions from 1918 to 1945. The other contributing structures are a recreation pavilion and service station, a switching building, a cargo ramp and three water tanks. A fence, main switchgear and electric substation are counted as non-contributing objects.

Senator Robert F. Broussard urged Quartermaster General Henry Granville Sharpe to place a supply depot at New Orleans for Gulf Coast regiments raised after the 1917 entry into World War I. Construction finished in 1919, one of thirteen Army depots then in the country. The 2005 Base Realignment and Closure Commission moved its units out; the base closed on September 15, 2011, and was sold to the City of New Orleans.

The buildings display early 20th-century industrial design with their functional architecture and structures. Walking through the complex shows how America built and operated its defense infrastructure during that period.

The site lies on the east bank of the Mississippi, near the Poland Avenue wharves rather than Dauphine Street. It is a working federal and city complex, not a museum, so access is limited to public roads and open grounds; check current use before planning a visit.

The base's warehouses were not always filled with munitions: between the two world wars the storage space was rented out to commercial firms. Of the nine contributing resources listed in 2016, three are original warehouses used for supplies and munitions from 1918 to 1945.
