Dunn is anunincorporated community in southwestTexas County, in theU.S. state ofMissouri.[1] The community is located just south ofU.S. Route 60, approximately four miles west ofCabool.[2]
A variant name was "Impo".[1] A post office called Impo was established in 1919, and remained in operation until 1955.[3] The present name is after the local Dunn family. The Postal Service rejected the proposed name of Dunn, so the post office became known as Impo (from Important), while the community retained the name Dunn.[4]
