The Webster State Park is a state park and recreation area in Stockton, Kansas. It features the Webster Reservoir and is adjacent to the Solomon River Valley.

The Webster State Park came into existence after the creation of the Webster Reservoir in 1958. The US Department of Interior Bureau of reclamation created the lake and the state park came to being in 1965. It is quite popular for wildlife viewing and bird watching, especially since its location is on the central flyway, meaning it is a stopping place for various species of waterfowl and shorebirds during their migration season.

Aside from these, hunting, camping, boating, fishing, hiking, swimming, RVing, and picnicking are also fairly commonly enjoyed at the Webster State Park.
