Boscobel (/ˈbɒskoʊbɛl/ BOSS-koh-bel)[3] is a city in Grant County, Wisconsin, United States.

(1 km) to the north of the city, across a riparian swamp, is the Wisconsin River.

Boscobel was the site of a stop along the now defunct Milwaukee Road, and it is still served by the Wisconsin and Southern Railroad.

[4][5] Businesses include the historic Central House Hotel, the birthplace of Gideons International.

[7] On August 7, 2021, the southern edge of Boscobel was hit by what would eventually become the strongest tornado in Wisconsin in more than a decade, reaching EF3 strength just east of the city.

The 2020 census population of Boscobel included 458 incarcerated people at the Wisconsin Secure Program Facility.

[9] This likely impacts the city's demographic and racial profile given that Wisconsin has the nation's highest racial incarceration gap and imprisons Black residents at twelve times the rate of white residents.

[10][11][12] At the 2010 census there were 3,231 people, 1,195 households, and 727 families living in the city.

The town was mentioned in the 1999 David Lynch biographical road drama film, The Straight Story when Iowa farmer Lyle Straight (played by Richard Farnsworth) asks a local priest if he knows the whereabouts of Lyle's brother (played by Harry Dean Stanton).
