The Pioneer Courthouse is a federal courthouse in Portland, Oregon, United States. Built beginning in 1869, the structure is the oldest federal building in the Pacific Northwest, and the second-oldest west of the Mississippi River. Along with Pioneer Courthouse Square, it serves as the center of downtown Portland. It is also known as the Pioneer Post Office because a popular downtown Portland post office was, until 2005, located inside.
