What is the name of Tony's mother?

Tony Soprano's mother is Livia Soprano, born Livia Pollio.

Livia is a major character in The Sopranos and is portrayed primarily by Nancy Marchand. She is the widow of Johnny “Johnny Boy” Soprano and the mother of Tony, Janice, and Barbara. Her difficult relationship with Tony is central to the early story: his childhood experiences and her manipulative behavior contribute to the emotional problems he explores in therapy with Dr. Melfi.

Livia is not simply a background relative. In the first season, her resentment, grievances, and conversations with Tony's uncle Junior become tied to a plot against Tony's life. Her influence helps expose the tension between Tony's private family and his position within the DiMeo crime family.

Series creator David Chase based much of Livia's personality and dialogue on his own mother, including her pessimism and sharp dismissiveness. The character later appears in flashbacks, with younger versions played by Laila Robins and Laurie J. Williams. Vera Farmiga portrayed a young Livia in the 2021 prequel film The Many Saints of Newark.
