Kittitas () is a city in Kittitas County, Washington, United States. The population was 1,381 at the 2010 census and an estimated 1,493 in 2018.
There are numerous interpretations of the name, which is from the language of the Kittitas American Indian language. According to one source, it “has been said to mean everything from ‘white chalk’ to ‘shale rock’ to ‘shoal people’ to ‘land of beauty’. Most anthropologists and historians concede that each interpretation has some validity depending upon the particular dialect spoken.”
Kittitas was established in 1883 and officially incorporated on December 9, 1931. It was founded as part of the westward expansion of the Chicago, Milwaukee, St. Paul and Pacific Railroad. The Kittitas Yard and Depot became the center of the community of Kittitas, one of the many small, agricultural towns that sprang up along the railroad lines. The railroad linked Kittitas to other small communities and the rest of the country, providing farmers and business people a way to sell their products in other towns and cities.
