The Mark O. Hatfield United States Courthouse is a federal courthouse in Portland, Oregon. It is named in honor of former U.S. Senator Mark O. Hatfield. It is used by the United States District Court for the District of Oregon.
The federal government originally planned to increase courtroom space in Portland by building a 13-story annex adjacent to the Gus J. Solomon United States Courthouse. In 1992, the government shifted to the construction of a new building across the street from the Multnomah County Justice Center, where federal prisoners are held for trial. The General Services Administration chose what was then known as the Hamilton Hotel block between Second and Third avenues and Salmon and Main streets for the courthouse.
