Columbia City was founded in 1867 by Jacob and Joseph Caples. In 1870, the town had aspirations of becoming the terminus for Ben Holladay's Willamette Valley railroad. The same year, Portland, Oregon, became the terminus of the west-side line, but the railroad never reached Columbia City. Columbia City post office was established in 1871. In 1902 the Columbia and Nehalem Valley Railroad was built as a forest railway towards Yankton.

Currently, Columbia City serves as a suburb of St. Helens.
