Rebecca Lynn Grassl Bradley (born August 2, 1971) is an American lawyer, and justice of the Wisconsin Supreme Court, serving since 2015.

[10] In May 2015, Walker elevated Bradley to the Wisconsin Court of Appeals to fill a vacancy caused by the death of Judge Ralph Adam Fine.

[14] After Crooks' death, Bradley, JoAnne Kloppenburg (who narrowly lost a race for the Wisconsin Supreme Court in 2011), and Joe Donald each announced their candidacy for the seat in the 2016 election.

[15] Bradley's homophobic writings as an undergraduate, published in 1992 in Marquette University's student newspaper, stirred controversy during the race.

[16][17] She had written letters to the editor and a column for the Marquette Tribune, in which she stated she held no sympathy for AIDS patients because they were "degenerates" who had effectively chosen to kill themselves.

[18] She attacked feminists as "angry, militant, man-hating lesbians who abhor the traditional family" and defended Camille Paglia, who had written in a 1991 column that "A girl who lets herself get dead drunk at a fraternity party is a fool.

[24] She was projected as the winner by a 53–47% margin on election night, and she quoted Winston Churchill at the end of her victory speech: "There is nothing more exhilarating than being shot at without result.

"[25] In June 2019, Bradley wrote the majority opinion for the Wisconsin Supreme Court when conservatives on the court upheld a series of laws, passed by the Republican-led Wisconsin legislature and Republican Governor Scott Walker during a lame-duck session, limiting the powers of the incoming Democratic Governor (Tony Evers) and Attorney General (Josh Kaul).

Bradley's dissent called the majority's decision not to overturn the election "an indelible stain" that would cause "significant harm to the rule of law".

[34] In 2021, Bradley wrote a majority decision for the Wisconsin Supreme Court declining changes in district maps that favored Republicans.
