Mom is an American television sitcom created by Chuck Lorre, Eddie Gorodetsky and Gemma Baker that aired on CBS from September 23, 2013, to May 13, 2021, lasting eight seasons. Set in Napa, California, it follows dysfunctional mother/daughter duo Bonnie and Christy Plunkett, who, after having been estranged for years while both struggled with addiction, attempt to pull their lives and their relationship together by trying to stay sober and attending Alcoholics Anonymous. It stars Anna Faris and Allison Janney in the leading roles, with Mimi Kennedy, Jaime Pressly, Beth Hall, William Fichtner, Sadie Calvano, Blake Garrett Rosenthal, Matt Jones, French Stewart and Kristen Johnston in supporting roles.

Filmed before a live audience, the series was produced by Chuck Lorre Productions and Warner Bros. Television. It received acclaim from critics and audiences throughout its run, with major credit given to its writing and performances (with Janney's noted in particular). It has been applauded for addressing real-life issues such as: alcoholism, drug addiction, teen pregnancy, addictive gambling, homelessness, relapse, cancer, death, erectile dysfunction, domestic violence, overdose, palsy, rape, obesity, stroke, ADHD and miscarriage; and for maintaining a deft balance between the humorous and darker aspects of these issues.

Mom consistently received high ratings in its genre, with an average viewership of 11.79 million, making it the third-highest rated comedy on broadcast television in the US; the show is among the top five comedies with adults aged 25–54 and adults aged 18–49. It received various accolades, with Janney winning two straight Primetime Emmy Awards for Outstanding Supporting Actress in a Comedy Series in 2014 and 2015, and being nominated in 2016 and for Outstanding Lead Actress in a Comedy Series in 2017, 2018, and 2021. It also garnered multiple nominations at the Critics' Choice Television Awards and the People's Choice Awards. On September 4, 2020, Faris announced she would exit from the series and shortly thereafter CBS announced that it would end after its eighth season. The series finale aired on May 13, 2021.
