Illinois Route 25 is a state road in northeast Illinois. It runs north from U.S. Highway 34 in Oswego to Illinois Route 62 (Algonquin Road) in Algonquin. Illinois 25 is 35.04 miles (56.39 km) in length.
Illinois Route 25 was opened in August 1929; it originally ran from Elgin to East Dundee. It was extended southward to St. Charles in 1930. The entirety of this road follows part of the Fox River on its eastern bank. Illinois Route 31 parallels Route 25 (and the river) on the western bank of the river.
Route 25's southern terminus is in Oswego. It moves northward into Montgomery, where U.S. Highway 30 passes over, but does not have an interchange with it. Route 25 then passes through downtown Aurora. It then winds through North Aurora and Batavia, lacking an interchange with Interstate 88. Route 25 intersects Illinois Route 56 in North Aurora, Illinois Route 38 in Geneva, and Illinois Route 64 in St. Charles.
