Rib Mountain, also known as Rib Hill, is a glacially-eroded monadnock in central Marathon County, Wisconsin, United States, located in the village of Rib Mountain southwest of downtown Wausau.

The peak is the site of transmitters for radio and TV stations in the Wausau area and is the namesake for Wisconsin Public Television's WHRM-TV and WHRM-FM, Wisconsin Public Radio's news and classical network station for the area. It also makes room for the transmitter at the top for WDEZ.
