Shannon Farnon is an American actress and voice actress. She is best known as being the first actress to voice Wonder Woman in a Hanna-Barbera production.
Born into a show business family, she is the daughter of Brian Farnon and Rita Oehmen, and sister of Charmian Carr and Darleen Carr. Her birthname is Sharon Farnon.
Farnon, while a teenager, went to theater art classes in Toronto and years later worked on commercial spots. The actress starred in film, TV, commercials and cartoons, however her first role came in 1965 in an uncredited role in Burke's Law. She went on to star in supporting roles in multiple other television series, but she was most active in the voice-over field in commercials. While doing a live-action commercial in 1973 for Flintstone vitamins she was approached by voice director Wally Burr to play what was to be her most famous role, Wonder Woman in Super Friends. She accepted.
From 1973 to 1983, the voice actress portrayed the heroine in Super Friends, Challenge of the Super Friends and The All-New Super Friends Hour. However in 1984, Farnon's prominent character was recast in The Legendary Super Powers Show, when the role was given to Constance Caufield and later to B.J. Ward. This case has often been given as an example of injustice in the television and animation industry.
Shannon Farnon voiced Wonder Woman on many Cartoon Network promos and went on to appear in several films and TV series, but since 2005, her acting appearances have been infrequent. She has married and has children.
