Joan Ganz Cooney is an American television writer and producer. She is one of the founders of Sesame Workshop, the organization famous for the creation of the children's television show Sesame Street, which was also co-created by her. Cooney grew up in Phoenix and earned a Bachelor of Arts in education from the University of Arizona in 1951. After working for the State Department in Washington, D.C., and as a journalist in Phoenix, she worked as a publicist for television and production companies in New York City. In 1961, she became interested in working for educational television, and became a documentary producer for New York's first educational TV station WNET. Many of the programs she produced won local Emmys.

Sesame Workshop, Inc. (SW), originally known as the Children's Television Workshop, Inc. (CTW), is an American nonprofit organization that has been responsible for the production of several educational children's programs—including its first and best-known, Sesame Street—that have been televised internationally. Television producer Joan Ganz Cooney and foundation executive Lloyd Morrisett developed the idea to form an organization to produce Sesame Street, a television series which would help children, especially those from low-income families, prepare for school. They spent two years, from 1966 to 1968, researching, developing, and raising money for the new series. Cooney was named as the Workshop's first executive director, which was termed "one of the most important television developments of the decade."
