The Chinook and Clatskanie Native Americans inhabited this region for centuries prior to the arrival of Robert Gray, captain of the ship Columbia Rediviva, in 1792. The Lewis and Clark Expedition traveled and camped along the Columbia River shore in the area later known as Columbia County in late 1805 and on their return journey in early 1806.
Columbia County was created in 1854 from the northern half of Washington County. Milton served as the county seat until 1857 when it was moved to St. Helens.
Columbia County has been afflicted by numerous flooding disasters, the most recent in December 2007. Heavy rains caused the Nehalem River to escape its banks and flood the city of Vernonia and rural areas nearby. Columbia County received a presidential disaster declaration for this event.

Politics
In Presidential elections the county was between 1930 and 2010 among the most consistently Democratic in the United States. The last Republican to win a majority in Columbia County had been Herbert Hoover in the 1928 presidential election, although before 1930 no Democrat had won a majority in the county since Samuel J. Tilden in 1876. However in 2016, Donald Trump won the county with just under fifty percent of the vote ending the tradition of choosing Democrats for president. That stated, the margin had been as little as three percent in 2004 and in 1984.
Columbia County is part of Oregon's 1st congressional district, which is represented by Suzanne Bonamici and has a Cook Partisan Voting Index score of D+8.
Economy
The primary industries are wood products and paper manufacturing, trade, construction and horticulture. The extensive stands of old growth timber, which had attracted many of the early settlers to the area, were completely logged over by the 1950s. Second-growth timber provides the raw material for local lumber and paper mills. About half the county's workforce commutes out of the county to work, most to the nearby Portland, Oregon, metro area. Columbia County's average nonfarm employment was 10,740 in 2007. The five largest private employers in Columbia County are Fred Meyer, Armstrong World Industries, Wal-Mart, Boise Paper, USIA, and USG.
