The Little Vermilion River is a 59.6-mile-long (95.9 km)[1] tributary of the Wabash River. The Little Vermilion rises in southern Vermilion County, Illinois, flowing eastward past Georgetown, Illinois, into Vermillion County, Indiana, where it joins the Wabash near Newport.[2]
There is a second river in Illinois that bears the same name: the Little Vermilion River (Illinois River tributary).
The Little Vermilion drains a small portion of northern Edgar County, Illinois. The watershed also extends into Champaign County, Illinois, via drainage ditches.
