Princeton is a small, unincorporated community located inside of Harney County in the state of Oregon. It is situated along Oregon Route 78 and is right between the towns of Burns Junction and Burns. The area has an elevation of 4,111 feet above sea level. The area started as nothing more than a rural post office around 1910. When Route 78 was upgraded, the community of Princeton was re-named New Princeton, a name it retains today.
