The Edwards River is a 73.7adj=midNaNadj=mid[2] tributary of the Mississippi River in northwestern Illinois in the United States. It rises 3miles west of Kewanee in southeastern Henry County and flows generally westwardly into Mercer County, where it joins the Mississippi 2miles southeast of New Boston. In Henry County it collects the South Edwards River, which flows past Bishop Hill.
The river was once home to a grain mill near Andover, Illinois. Several sections of the Edwards River's course have been straightened and channelized.
