Betsey Johnson (born August 10, 1942) is an American fashion designer best known for her feminine and whimsical designs. Many of her designs are considered "over the top" and embellished. She also is known for doing a cartwheel at the end of her fashion shows.

Johnson is the second of three children born to Lena and John Johnson. She has an older sister, Sally, and a younger brother, Robert. Johnson took many dance classes, which inspired her love of costumes. Following her graduation from high school, Johnson studied at the Pratt Institute and then later graduated Phi Beta Kappa from Syracuse University where she was a member of the Alpha Xi Delta women's fraternity. After graduation, she spent a summer as a intern at Mademoiselle magazine.

Johnson's fashion career started after she entered and won the Mademoiselle Guest Editor Contest. Within a year, she was the in-house designer for Manhattan boutique Paraphernalia. Johnson became part of both the youthquake fashion movement and Andy Warhol's underground scene, along with The Velvet Underground, Edie Sedgwick and Lou Reed. In 1969, she opened a boutique called Betsey Bunky Nini on New York's Upper East Side. Edie Sedgwick was her house model and Johnson designed the clothing Sedgwick wore on her last film, Ciao! Manhattan.^{[citation needed]}
