Miss Piggy is a Muppet character known for her breakout role in Jim Henson's The Muppet Show. Since her debut in 1976, Miss Piggy has been notable for her volatile diva personality, tendency to use French phrases in her speech, and practice of karate. She was also known for her on-again/off-again relationship with Kermit the Frog, which began in 1978 and has been on a hiatus since 2015. Frank Oz performed the character from 1976 to 2000 and was succeeded by Eric Jacobson in 2001.

Since the debut of The Muppet Show, the romantic relationship between Miss Piggy and Kermit the Frog has been subject to substantial coverage and commentary by the media. Throughout The Muppet Show's run, Miss Piggy's romantic pursuit for Kermit was consistently expressed. Kermit, however, constantly rebuffed Piggy's feelings. Eventually, in the films, Kermit began returning her affections and even (unwittingly) marries her in The Muppets Take Manhattan. However, subsequent events suggest that the marriage was simply fictional. It is mentioned by Miss Piggy, however, in The Muppets: A Celebration of 30 years (1986) that Kermit was a happily-married frog. This marriage isn't referenced in Muppets Most Wanted and the two get married again in this film.  Miss Piggy and Kermit formally ended their romantic relationship on May 10, 1990. The decision was made by Jim Henson Productions and a publicity campaign titled "The Pig of the Nineties" was scheduled to follow. An autobiography of Piggy was expected to be published as part of the effort. However, shortly after the announcement on May 16, Jim Henson died and the campaign was dropped altogether. The two eventually resumed their relationship.  In 2015, Miss Piggy and Kermit ended their romantic relationship for a second time. Some commentators said the relationship should end permanently since she regularly abused him. "In the end, it's better for everyone that Kermit and Piggy have gone their separate ways. For the frog, it means the end of a long, abusive relationship," wrote Noah Berlatsky in The New Republic. "Kermit continually lives in fear of his girlfriend, knowing that even simple misunderstandings or slips of the tongue will result in Miss Piggy erupting like a porcine Vesuvius," dating coach Harris O'Malley wrote in The Daily Dot. "On at least three separate incidents, she attempts to coerce Kermit into a relationship, beating him when he refuses. Other times she reacts with violence and rage whenever Kermit commits the 'sin' of breaking up with her, simply hugging a friend, talking to a woman, or even just standing too close to them."
