Peshastin is a small unincorporated community in Chelan County, Washington, United States.

The community's roots are found in the "Peshastin Ditch" dug by pioneers beginning in 1889.

This ditch was an important part of the overall irrigation system in the area, delivering water to the orchards on the slopes above Cashmere.

[4] Today, Peshastin is still a small community with one elementary school and a library.

[5][6] Peshastin is located in the valley of the Wenatchee River with the communities of Leavenworth upstream and Dryden downstream.
