The Apple River is a tributary of the Mississippi River, about 55 miles (89 km) long,^[2] in southwestern Wisconsin and northwestern Illinois in the United States. It rises in Lafayette County, Wisconsin, and flows for most of its length in Illinois, through Jo Daviess and Carroll Counties. Along its course it passes through Apple River Canyon State Park and the town of Hanover. It flows into the Mississippi River about 7 mi (11 km) northwest of Savanna.

In Jo Daviess County, it collects two short tributaries known as the West Fork Apple River and South Fork Apple River.
