Roseanne Cherrie Barr (born November 3, 1952) is an American actress, comedian, writer, and television producer. Barr began her career in stand-up comedy at clubs before gaining critical and popular acclaim in the television sitcom Roseanne (1988–1997; 2018). She won both an Emmy and a Golden Globe Award for Best Actress for her work on the show.

Barr was born into a Jewish family living in Salt Lake City, Utah. She became a standup comedian in 1980. In the late 1980s and early 1990s, she began to emerge as a celebrity through her role in Roseanne and other public performances. Barr sparked controversy when performing "The Star-Spangled Banner" at a nationally aired baseball game on July 25, 1990. After singing the anthem in what many perceived to be a deliberately disrespectful manner, Barr grabbed her crotch and spat. This performance was met with condemnation from baseball fans and sportswriters, and was called "disgraceful" by then-President George H. W. Bush.

Barr has been active and outspoken on political issues. She won nearly 70,000 votes for president in the general election of 2012, as the presidential nominee of the Peace and Freedom Party. After Donald Trump announced his candidacy for president in 2015, Kelly Weill of The Daily Beast wrote that Barr "veered right" in her politics. After Roseanne was revived, Trump called her to congratulate her on her show's ratings and thank her for her support. She has frequently defended her support of Trump, and has been criticized for her extensive use of personal attacks, conspiracy theories, and fake news.

Roseanne was revived in 2018 on ABC; the show was abruptly canceled on May 29, after being renewed for another season, due to Barr making a controversial tweet, which many called "racist" and she later called a "bad joke".
