History

The name of the city is taken from the Tualatin River, which flows along most of the city’s northern boundary. It is probably a Native American word meaning “lazy” or “sluggish” but possibly meaning “treeless plain” for the plain near the river or “forked” for its many tributaries. According to Oregon Geographic Names, a post office with the spelling “Tualitin” was established November 5, 1869, and the spelling changed to “Tualatin” in 1915.

In the 1850s, the settlement was first called Galbreath after its founder Samuel Galbreath. In 1853, Galbreath built the first bridge over the Tualatin river, and the town became known as Bridgeport. In the 1880s, John Sweek platted a town around the new railroad depot, and named the town Tualatin. It was incorporated as the City of Tualatin in 1913.

In 1962, a fossilized Mastodon (Mammut americanum) was excavated in what is now the Fred Meyer parking lot. It is now on display in the lobby of Tualatin Public Library. In 1972 fossils were uncovered near Fanno Creek that were determined to be a partial skeleton of a Harlan’s Ground Sloth (Paramylodon harlani).
