State Trunk Highway 47 (often called Highway 47, STH-47 or WIS 47) is a 188.01-mile (302.57 km) state highway in the northeastern and northern parts of the US state of Wisconsin that runs in a diagonal northwest–southeast from Menasha to Manitowish.

The southern terminus of WIS 47 is at WIS 114 at the corner of Third and De Pere streets in Menasha.

After a solo segment, WIS 47 follows US Highway 45 (US 45) from south of Antigo to Monico and US 8 from Monico to Rhinelander.

In 1919, the highway was expanded north to Antigo, where it ended at US 45.

In 1997, freeway was added with the WIS 29/WIS 55 bypass near Bonduel.
