List of recurring The Simpsons characters

The American animated television series The Simpsons contains a wide range of minor and supporting characters like co-workers, teachers, students, family friends, extended relatives, townspeople, local celebrities and even animals. The writers intended many of these characters as one-time jokes or for fulfilling needed functions in the town of Springfield, where the series primarily takes place. A number of these characters have gained expanded roles and have subsequently starred in their own episodes. According to the creator of The Simpsons, Matt Groening, the show adopted the concept of a large supporting cast from the Canadian sketch comedy series Second City Television.

This article features the recurring characters from the series outside of the five main characters (Homer, Marge, Bart, Lisa and Maggie Simpson). Each of them are listed in order by their first name.

Agnes Skinner

Agnes Skinner (voiced by Tress MacNeille in most appearances, Maggie Roswell in "Lisa's Rival") is the mother of Principal Skinner and first appears in the first-season episode "The Crepes of Wrath" as an old woman who embarrassingly addresses her son as "Spanky". However, as episodes progress, her character turns bitter. She is very controlling of her son and often treats him as if he is a child, insulting and ridiculing him every chance she gets. Despite him saving her from danger, Skinner hates her because she is still controlling him.
