Maggie Sheffield is a principal character in the long-running sitcom, The Nanny. She is portrayed by Nicholle Tom.
Margaret is the eldest daughter of Maxwell Sheffield (Charles Shaughnessy) and Sara Sheffield (Bess Armstong). At first, she felt shy and awkward, and despaired that no boy would ever fall for her. She was forever bickering with her brother, Brighton Sheffield, who felt that she was a nerd. She thought of him as a troll. Her relationship with her youngest sister, Gracie Sheffield was one as a mentor. Maggie gained two more siblings when the twins Eve Sheffield and Jonah Sheffield were born in the final season of the show.
Then, Fran Fine (Fran Drescher) was hired as the new nanny. Fran and Maggie bonded almost instantly and had a close relationship. Under Fran's patient tutelage, she blossomed from a shy and awkward teenager to a very beautiful young woman. In her father's eyes, she is every bit as beautiful as her mother was.
In school, she and Fran had discovered that her gym coach was the same coach that had tormented Fran when she was Maggie's age. Maggie knew her as Coach Stone, but Fran knew her better as Ms. Wickavich. Ms. Wickavich was a bully, who had no liking for either Maggie or Fran, and tormented and taunted both until she choked on her whistle, whereupon Fran, her former student, saving her life. She grudgingly passed Maggie in Gym.
Her father tended to smother her way too much, discouraging her from any kind of activities with boys. It was the "Daddy's little girl" syndrome. He wanted her to remain his little girl, and he couldn't stand it that she was growing up.
When Fran and her father married, Maggie was one of her maids-of-honor. She bonded well, even before the marriage, to Fran's mother, Maggie's soon-to-be grandmother, Sylvia Fine and her soon-to-be great-grandmother, Yetta Rosenberg.
Eventually, Maggie met and married an underwear model named Michael (Andrew Levitas), who was related, by marriage, to Barbra Streisand (his cousin was James Brolin, Ms. Streisand's husband). This made Maggie the only one of the three Sheffield children to get married during the show's run. At the pre-ceremony (with guests of honor being Ms. Streisand and her husband), Fran experienced premature labor pains, and had to go to the hospital. Then Fran snuck out of the hospital, just as Maxwell had everyone else come to the hospital to see Fran, including Babra Streisand. Dismayed by the failure of her plan, Fran sobbed over the phone. Maggie's wedding was postponed to the next day. In the final episode, Maggie and her husband moved to Europe, where he had a modeling shoot in Venice, but she stayed in Paris with Brighton.
- In Fran Drescher's first book, Enter Whining, Fran explained that Maggie was added later, at the suggestion of a network exec, and wasn't part of the original family, but was said that a shy teenager would be a funny contrast to a brazen and flashy Fran, hence the addition of Maggie.
