Casa Rio (also been known as the S.W. Stribley House) is a house that was built in 1945. It was designed by architects Henry Van Ryn and Gerrit de Gelleke in the Mission/Spanish Revival style. It was listed on the National Register of Historic Places (NRHP) in 1996; the listing included one contributing building and two contributing structures on 2.3 acres (0.93 ha).
Van Ryn and de Gelleke worked mostly in Wisconsin; the Charles W. Stribley House in Kaukauna, Wisconsin, built in 1910, is another of their works that is NRHP-listed.
