FanDuel Sports Network Wisconsin is an American regional sports network owned by Main Street Sports Group (formerly Diamond Sports Group) and operated as an affiliate of FanDuel Sports Network. Operating as the "Wisconsin" sub-feed of Fox Sports North until 2007, the channel was known as Fox Sports Wisconsin until 2021. It broadcasts regional coverage of sports events throughout the state of Wisconsin, with a focus on professional sports teams based in Milwaukee, namely Major League Baseball's Milwaukee Brewers and the Milwaukee Bucks of the National Basketball Association. It primarily operates from a studio/office facility in downtown Milwaukee, with secondary offices and production studio/office hub based in downtown Minneapolis, Minnesota.

FanDuel Sports Network Wisconsin is available on cable providers throughout Wisconsin, extreme eastern Minnesota, the western Upper Peninsula of Michigan, northwestern Illinois, and Iowa; it is also available nationwide on satellite via DirecTV.

FanDuel Sports Network Wisconsin broadcasts 2,600 hours of locally produced programming per year and reaches more than 1.7 million homes.

The first effort to air the Bucks and Brewers on cable, Sportsvue in 1984, was hampered by multiple factors, including dispersed systems and uncabled parts of the state of Wisconsin (including Milwaukee itself), team nadirs for the Bucks and Brewers and the availability of Chicago Cubs games via superstation WGN-TV throughout the state. Sportsvue was discontinued at the beginning of 1985 and resulted in the sale of the Bucks to future senator Herb Kohl. In the meantime, the Bucks and Brewers returned to a statewide broadcast network originated by Gaylord Broadcasting's WVTV, and later WCGV-TV, which was hampered by the two teams limiting their schedule to mainly road games.

Wisconsin Sports Network (unrelated to the current-day high school-focused sports publishing operation), a gametime-only network that broadcast Milwaukee Brewers baseball and Milwaukee Bucks basketball games. The channel was owned by Time Warner Cable's Milwaukee franchise and Group W. In 1996, it was taken over by the Minneapolis-based Midwest Sports Channel (MSC), which was owned by CBS (as a result of CBS' 1995 merger with Group W's corporate parent Westinghouse). Shortly afterward, MSC became an affiliate of the fledgling Fox Sports Net in the fall of 1996.

From then on until 2007, Wisconsin was served by one of three regional subfeeds of MSC/FSN North; the other two being a feed for the Twin Cities metropolitan area and a feed for the rest of Minnesota (as well as Iowa, North Dakota and South Dakota). CBS sold the network to News Corporation in 2000, ultimately rebranding as FSN North in April 2001. Despite being well out of the station's market area, MSC's late night encore of WCCO's 10:00 p.m. newscast also aired on the Wisconsin network until the Fox purchase. The network then began maintaining offices at the studios of Fox owned-and-operated station WITI (channel 6, now an affiliate of the network) in the Milwaukee suburb of Brown Deer, along with sharing limited programming with that station.

FSN North converted the Wisconsin feed into a separate channel, FSN Wisconsin. The channel launched on April 1, 2007, coinciding with the start of the 2007 Milwaukee Brewers season, originating from facilities in Milwaukee. That year it aired 125 Brewers games and 70 Bucks games. Other programming included the Minnesota Wild (NHL), University of Wisconsin athletic events, WIAC events, and WIAA high school sports, including live telecasts of the annual football championships. At launch FSN Wisconsin was available to more than 1.5 million homes and produced nearly 2,600 hours of local programming.

After Fox Television Stations sold WITI to Local TV in 2008, FSN Wisconsin relocated its operations to facilities in downtown Milwaukee. As part of the national rebranding of the Fox Sports Networks in 2012, FSN Wisconsin was rebranded as Fox Sports Wisconsin.
