The Tortellis
- Nick Tortelli (Dan Hedaya) – Carla's scumbag first husband, who occasionally stopped by Cheers for one reason or another. Nick married Loretta in season 2 episode "Battle of the Exes". Nick was generally used as comic relief, appearing as a caricature of a deadbeat dad and ex-husband, and a negative stereotype of Italian-Americans. This was sometimes taken to extremes, Frasier once asking if Nick was featured at a World's Fair as a missing link. Nick has on occasion tried to reunite with Carla, without success.
- Loretta Tortelli (Jean Kasem) – Nick's blond airhead wife, who was generally a side character despite significant screen time. Although Nick tries to rub his new wife's beauty in Carla's face, Carla becomes friends with Loretta as she begins to notice Nick's horrible characteristics. Loretta's dream, before she married Nick, was to become a singer; she once described herself as a "taller, blonder, less Mormon Marie Osmond". However, Loretta lacked in talent, though she performed with two groups, "The Grinning Americans" (described as an Up with People-type group) and The Lemon Sisters (deliberately named to be confused with The Lennon Sisters).
- Loretta was also featured in the short-lived spin-off series, The Tortellis; Nick was the main character.
- Anthony Tortelli – Carla's eldest child. He first appeared wanting Carla's permission to marry his girlfriend when they were both only 16 years old.
- Serafina Tortelli – Carla's eldest daughter. She becomes pregnant by a retired police officer.
- Gino Tortelli – To keep the family peace between Carla and her mother, he agrees to keep the family tradition alive and change his name to Benito Mussolini. Carla refuses.
- Anne Marie Tortelli
- Lucinda Tortelli
Carla also has 3 more children that are not fathered by Nick
- Bennett "Lud" Ludlow, Jr. (Carla's son with Dr. Bennett Ludlow)
- Elvis Lebec and Jesse Lebec (Carla's twin sons with Eddie Lebec)
