Welcome to the official site of the Town of Erin, Washington County, Wisconsin. The town is nestled in the beautiful kettle moraine area of southeastern Wisconsin. The variety of topography makes the town very unique. We also have the highest point in southeastern Wisconsin, on which Basilica of Holy Hill, National Shrine of Mary sits.
While we are not the first town settled in Washington County, we are the oldest town, and the first one to incorporate by act of the Territorial Legislature on January 16, 1946. The fitting name "Erin" was suggested by John Whelan.
The town is located in the far southwestern corner of Washington County. It is 36 square miles and has approximately 3790 residents. The town is a mix of agricultural and residential, but is predominately rural. The town includes the unincorporated hamlet of Thompson. There are several lakes in the town including Druid, Loew's, Murphy, McConville, Malloy, Beck, and Hickey Lake. The two major rivers in the town are the Oconomowoc and Ashippun Rivers. Smaller rivers and creeks include the Little Oconomowoc River, Flynn Creek, and Mason Creek.
We are bordered on the west by the Town of Ashippun/Dodge County, south by
Town of Merton/Waukesha County, east by the Town of Richfield, and north by the
Town of Hartford.
More information will continue to be added to the website to make it more useful and helpful for you.
