Jo Ann Pflug (born May 2, 1947 in Atlanta, Georgia) was an American motion picture and television actress before retiring from acting in the 1980s.

Pflug was in the film MASH (1970) as the U.S. Army nurse Lt. Maria "Dish" Schneider. Also, in 1978–79, she played an Army nurse in the second season of the U.S. Navy-submarine-based TV series Operation Petticoat. This series had undergone an almost complete change of cast after its successful first 1977–78 season, and it did not last very long in 1979, when it was canceled.

Pflug was also a frequent panelist on the television game-show Match Game in 1973–81, a co-host with Allen Funt on the 1970s version of Candid Camera, and a regular on the TV series The Fall Guy in 1981-82. In 1984, she was the first actress to play Taylor Chapin on the unsuccessful soap Rituals.

Pflug's only marriage was to game show host Chuck Woolery. Pflug was Woolery's second wife. The couple married in 1971 and divorced in 1981. Woolery has since married a third time.

Pflug is a graduate of the University of Miami in Coral Gables, Florida. A born-again Christian, she has a daughter, Melissa, with Woolery.

Now tours with her own motivational seminars.

Turned down the Valerie Perrine role in the film Slaughterhouse-Five (1972) due to its sexual content. For different reasons, she also turned down the Bonnie Franklin mom role in the TV sitcom "One Day at a Time" (1975).

Became a born-again Christian and abandoned her career for the most part.

Despite the fact that a large portion of her role was left on the cutting room floor, she still made a spectacularly sexy impression in the cult movie hit MASH (1970), which led to numerous TV co-star roles.
