Nancy Bartlett, portrayed by actress Sandra Bernhard (#Bi2), is a character in the American television sitcom Roseanne, created by Matt Williams. The show originally aired on ABC from 1988 to 1997 and saw a brief revival for a season in 2018.

Nancy is a close friend of the Conner family, known for her distinct personality, wit, and unique sense of style.

Nancy is the girlfriend, then the estranged wife, of Arnie Thomas (played by comedian Tom Arnold, Roseanne Barr's husband at the time), one of Dan's poker buddies, on Roseanne.

As the series progresses, Nancy's character undergoes significant development, and one aspect that contributes to her complexity is her bisexuality.

Nancy's bisexuality is an integral part of her character, and the series portrays it with a nuanced and authentic approach. As a bi woman, Nancy navigates her relationships and experiences with a genuine and unapologetic demeanor. The representation of Nancy's bisexuality in "Roseanne" is notable for its time.
