Lemonweir is an unincorporated community located in the town of Lemonweir, Juneau County, Wisconsin, United States. Lemonweir is located on County Highway N 3miles east-southeast of Mauston.[1] Known locally as "Lemonweir Mills," it was once an important mill settlement on the Lemonweir River, as the name suggests. It once rivaled Mauston in size and potential until the railroad bypassed it. Aside from a few houses, nothing now remains.
