Camp Abbot, Military training complex in Central Oregon, United States.

Camp Abbot was a military training complex with barracks, practice grounds, and engineering facilities spread across a large area near the Deschutes River. Today the land holds a resort community, while the main hall built from local pine and stone remains as an event venue.

The facility opened in 1943 and trained tens of thousands of combat engineers for deployment during World War II until 1944. After the war ended, the site was gradually converted for different uses.

The officers' mess hall, built in 1943 by the Army Corps of Engineers under Captain John V. Banks, is the only original Camp Abbot building left. It now serves as Sunriver Resort's Great Hall for conferences, banquets and weddings, and was renovated in 1993.

The Great Hall stands at its original site within Sunriver Resort, about 15 miles south of Bend off U.S. Highway 97; the resort has an executive airport. The hall is used for conferences, banquets and weddings, so check event bookings before planning a look inside. The surrounding former camp land is now national forest and private homes.

The camp hosted the Oregon Maneuver, the largest military field exercise ever held in the Pacific Northwest, with over 100,000 troops. Its General Patch Bridge, built in 1943, was demolished by the Forest Service in 2008 as unsafe.
