Foster Junction is an unincorporated community located in Ashland County, Wisconsin, United States. The community was named for George E. Foster, a partner in the Mellon Lumber Company. The company founded Foster Junction in 1910.[1]
Foster Junction failed to thrive, and many of its buildings were dismantled and relocated to Mellen.[1] Foster Junction no longer had any residents by the 1930s.[2]
