Sandra Corleone is a fictional character appearing in Mario Puzo's novel The Godfather, the Godfather film trilogy, and the Godfather video game. She was portrayed by Julie Gregg in the first Godfather film.
Born in the 1920s, she married Sonny Corleone and mothered their four children:
Despite Sonny being married to her, he was a womanizer, and had a mistress, Lucy Mancini, with whom he fathered his youngest son Vincent Mancini-Corleone. Vincent would grow up to succeed Michael as the Don of the Corleone family in The Godfather Part III.
In the novel, further details of Sandra's life are given, calling her a large-breasted woman who immigrated from Italy when she was just a child. She is unable to tolerate having sex with her husband, due to his excessively large penis; she is aware, and apparently thankful, that he is a womanizer. She and Sonny live in a house in the Corleone Mall. After Sonny's death, she takes her children to live with her parents in Florida.
Sandra appears in a deleted scene in The Godfather Part II, trying to gain her brother-in-law Michael's blessing for Sandra's daughter Francesca's engagement. Michael approves but suggests that her fiance change his college studies. In a deleted subplot, Sandra becomes Tom Hagen's mistress, a fact that Michael uses to blackmail Hagen into remaining loyal to the family, despite Sandra urging Hagen to abandon the Corleone family.
