Long known as part of the large Ojibwe territory, the county was founded by European Americans in 1840 and organized in 1855. Settlers were attracted by access along the White River, which reaches its mouth on Lake Michigan in Muskegon County to the south. Oceana County is thought to be named for Lake Michigan, a freshwater \"ocean,\" which forms its western border. Clarke said it was named for the book Oceana, written by English author James Harrington in 1656. Oceana County is famous as the \"Asparagus Capital of the World\" for its high production of asparagus. The annual Asparagus Festival includes a parade and crowning of the Asparagus Queen. In 1960, Robert H. Woody was the first psychologist in the area, working for the Oceana Intermediate School District.
