Mary Frances Crosby (born September 14, 1959) is an American actress. She is most often credited as simply Mary Crosby for her performances.

She was born in Los Angeles, California. She is the daughter of the singer and actor Bing Crosby, from his second marriage to the actress Kathryn Grant. She graduated from high school at 15. She then entered the University of Texas at Austin where she became a member of Delta Delta Delta sorority, but dropped out of the University before graduating. She is fluent in Spanish.

She has been twice married:

Crosby may be most noted for her role as Kristin Shepard (Sue Ellen Ewing's scheming sister) on the TV series Dallas from 1979 to 1981. Her character is perhaps best remembered for her part in the cliffhanger ending of the 1979-1980 season of Dallas, entitled "A House Divided", that was resolved in the fourth episode of the following season, "Who Done It". In that highly watched episode, J.R. Ewing, (played by Larry Hagman) was shot by an unknown assailant. Viewers had to wait all summer (and most of the fall due to a Hollywood actors' strike) to learn whether J.R. would survive, and which of his many enemies was responsible. During the summer of 1980, the question, "Who shot J.R.?", was being asked in everyday conversations around the world. Ultimately, Kristin Shepard (Crosby) was revealed to have been the person who pulled the trigger in the classic "Who Shot J.R.?" episode that aired on November 21, 1980. It was one of the highest-rated episodes of a TV show ever aired.
