Susan Delfino

Susan Delfino (née Bremmer, formerly Mayer) is a fictional character played by Teri Hatcher on the American Broadcasting Company (ABC) television series Desperate Housewives. The character was created by television producer and screenwriter Marc Cherry. She first appeared in the pilot episode of the series on October 3, 2004, and appeared in every episode until the series finale on May 13, 2012. Susan resides on the fictional Wisteria Lane in Fairview, Eagle State, the primary setting of the show. One of four lead characters, Susan is characterized as being a "notoriously clumsy" romantic with a "magnetic charm." Her storylines tend to focus on her romantic relationships, most notably with Mike Delfino (James Denton), whom she marries twice in the series.

Cherry originally created Susan as a girl next door archetype and intended for the character to provide an emotional anchor for the series. When developing the character, Cherry drew upon his personal experiences as well as those of single women in his life. The role was originally written for Mary-Louise Parker, who turned it down; as a result, Hatcher was cast in early 2004. Hatcher's portrayal of the character is both comedic and vulnerable. During the series' debut season, both the character and Hatcher's performance received positive critical reception; however, as the series has progressed, the character has been received less favorably by critics and fans. Hatcher has received both a Golden Globe Award and Screen Actors Guild Award for her performance in the series.
