Wenatchee Confluence State Park, State park at the Wenatchee–Columbia river confluence in Wenatchee, Washington, United States.

Wenatchee Confluence State Park covers 197 acres (80 ha) at the north end of Wenatchee, where the Wenatchee River enters the Columbia River. The river divides it into a northern section in Sunnyslope with camping, boating, fishing, swimming and sports facilities, and a southern section in West Wenatchee that forms the man-made Horan Natural Area wetland. A footbridge links the two halves.

Wenatchee Confluence State Park was established in 1990 as a recreation and bird sanctuary at the mouth of the Wenatchee River. The land is owned by the Chelan County Public Utility District and operated by Washington State Parks under a lease. The south section was built as a man-made wetland, now the Horan Natural Area.

The park's name comes from the Wenatchee River meeting the Columbia River. The south section is the Horan Natural Area, a man-made wetland of marshland, channels and islands where muskrats, beavers and over 200 bird species have been recorded, including swallow-tailed kites, storm petrels and Aztec terns.

The Wenatchee River splits the park into a north and a south section, joined only by a footbridge, so plan which side you want before crossing. The Horan Natural Area wetland lies in the south section; the north section in Sunnyslope holds the camping, swimming and sports facilities. The Apple Capital Recreation Loop Trail links the park to downtown Wenatchee.

The park is split by the Wenatchee River into two halves joined by a footbridge, and from that bridge visitors can watch bald eagles, common loons, and Eurasian wigeons. The south half is a man-made wetland, the Horan Natural Area, where muskrats and beavers live among channels and islands.
