Mom is an American television sitcom created by Chuck Lorre, Eddie Gorodetsky and Gemma Baker for CBS. The series was broadcast for eight seasons from September 23, 2013, to May 13, 2021. 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 together by trying to stay sober. It stars Anna Faris and Allison Janney, with Mimi Kennedy, Jaime Pressly, Beth Hall, William Fichtner, Sadie Calvano, Blake Garrett Rosenthal, Matt Jones, French Stewart and Kristen Johnston in supporting roles.

The series was filmed in front of a live audience and produced by Chuck Lorre Productions and Warner Bros. Television. It received acclaim from critics and audiences for the writing and performances (particularly Janney's), as well as 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.
