List of Oregon judges

The judges of the Oregon circuit courts, who generally serve a single county, are not listed.

John Kirk Townsend is recorded to have served as a judge prior to the establishment of the Provisional Government of Oregon.

No formal judicial system existed in the region prior to February 18, 1841, when settlers at the Champoeg Meetings, in their effort to form a Provisional Government, elected Babcock as Supreme Judge as well as four justices of the peace and a High Sheriff as minor executive position, while they failed to establish the introduction of a governor because of discontent by French-Canadian settlers.

On May 2, 1843, the Provisional Government of Oregon was finally created through a narrow 52–50 vote under the English American and French Canadian settlers.

This includes judges who have been assigned to the Ninth Circuit Court of Appeals' duty station at the Pioneer Courthouse in Portland, Oregon.
