Trentwood was a community and former census-designated place (CDP) in Spokane County, Washington, United States, east across the Spokane River from Irwin. The population was 4,388 at the 2000 census. Trentwood joined the other unincorporated communities in the region to form the city of Spokane Valley in 2003.


Trentwood was originally called East Trent because of its position across the Spokane River from Irwin, formerly named Trent. Rather than a centralized town, East Trent was a loose collection of communities including a rail station named Steno, after a local court stenographer, and Trentwood Orchards, so named because of an economy of lumber and fruit trees. In 1917, after the stenographer died as well as many of the fruit trees, the railroad and communities came together under the name Trentwood.[3]
