The Chiwawa River is a tributary of the Wenatchee River in Chelan County , Washington state .

Much of the catchment area of ​​the Chiwawa River is designated as a national forest and a wilderness area. The upper catchment area is in an almost natural state.

The river is part of the Columbia River system by flowing into the Wenatchee River, which is a tributary of the Columbia River.

The name of the river comes from the Columbia-Moses and means a special kind of river ( creek ) - a "wawa" creek. A large number of field names in the Chiwawa River catchment area come from Albert H. Sylvester .
