The Glacial Drumlin State Trail is a multipurpose rail trail in the U.S. State of Wisconsin. It stretches 52 miles (84 km) from Waukesha (near Milwaukee) to Cottage Grove (near Madison). The trail travels through or near the Wisconsin communities of Cottage Grove, Deerfield, London, Lake Mills, Jefferson, Helenville, Sullivan, Dousman, Genesee, Wales, and Waukesha. In Lake Mills, it crosses Rock Lake on one of its many old railroad bridges. The trail was opened in 1986 and follows the old Chicago and North Western Railway (C&NW) Madison–Milwaukee mainline.

The name refers to a drumlin, a glacial landform very common in the area.
