WMSN-TV (channel 47) is a television station in Madison, Wisconsin, United States, affiliated with the Fox network.

Owned by Sinclair Broadcast Group, the station has studios on Big Sky Drive on the west side of Madison, and its transmitter is located on South Pleasant View Road in the Junction Ridge neighborhood also on Madison's west side.

It was the first new commercial station to launch in the Madison market since WISC-TV signed on thirty years earlier.

One of WMSN's earlier programs was Big Sky Theater, a Saturday night presentation of classic movies (mostly westerns) from the drive-in era.

The station was originally owned by Channel 47 LP, a group of investors led by Ronald J. Koeppler.

In July 2014, the channel was reactivated as an affiliate of GetTV, which would be replaced on October 31, 2015 by Sinclair-owned sci-fi network Comet.
