The District of Oregon was a Union Army command department formed during the American Civil War.
The District of Oregon was part of the independent Department of the Pacific reconstituted by consolidating the Departments of California and Oregon, which was created on January 15, 1861 when the Army was reorganized. The district was created the same day, and comprised the same territory as the former Department of Oregon, the state of Oregon (except for the areas of the Rogue River and Umpqua River in Southern Oregon) and Washington Territory, with headquarters at Fort Vancouver in Washington Territory.
On March 3, 1865 the district included Idaho Territory after it was formed from the eastern part of Washington Territory. On March 14, 1865, the District of Oregon was extended to include the entire state of Oregon.
On July 27, 1865 the Military Division of the Pacific was created under Major General Henry W. Halleck, replacing the Department of the Pacific. It consisted of the Department of the Columbia replacing the District of Oregon and the Department of California. George Wright, now a U. S. Army Brigadier General, was assigned to command the new Department of the Columbia.
