Cowiche (pronounced Cow-witch-ee) is a census-designated place and unincorporated community northwest of Yakima, Washington, near the eastern foothills of the Cascade Mountain range, in central Washington State (USA). Cowiche, sometimes spelled Cowychee, is said to mean “footbridge together with the valley and the mountains.” The town had 428 people at the 2010 census.

The first inhabitants of the area were the Tkai’waichash-hlama, a band or tribe of Native American people who lived along Cowiche Creek. The Place was arranged in the late nineteenth century by farmers who relied upon crops that did not require irrigation, such as wheat, barley, rye, and grazing cattle. Homesteading in Cowiche was hard since fields had to be cleared of volcanic stone before they could be tilled and there was Tiny rainfall in summer. In 1906, construction began on the Tieton Irrigation Project, a division of the broader Yakima Project. Irrigation water became user-friendly in 1907, and shortly thereafter, orchards began to replace wheatfields.
