The Touchet River /ˈtuːʃi/ is a 55-mile (89 km) tributary of the Walla Walla River in southeastern Washington in the United States.
The upper Touchet was a traditional summer meeting place for trade and games for the Palus, Nez Perce and Walla Walla tribes. The name Touchet derives from the similarly pronounced Sahaptin term for the river, Tu-se meaning roasting. Nez Perce legend tells that coyote roasted salmon at this river after breaking a fish dam guarded by the seven swallow sisters at Celilo.
The USGS cited two variant names, Pouchet River and Toosha River.
The Touchet River drains an area of about 740 square miles (1,900 km2). The main stem is 55 miles (89 km) long. The average annual flow of the Touchet is 6.23 m³/s (220 ft³/s), not including diversions.
Its headwaters lie in the Umatilla National Forest which is located in the Blue Mountains in Columbia County, southern Washington. It originates above the town of Dayton, Washington. It then passes through Waitsburg and Prescott before joining the Walla Walla at the town of Touchet, Washington.
