The fourth season of the situational comedy drama Mom began airing on October 27, 2016, on CBS in the United States. The season is produced by Chuck Lorre Productions and Warner Bros. Television, with series creators Chuck Lorre, Eddie Gorodetsky and Gemma Baker serving as executive producer. The season concluded on May 11, 2017.

Christy (Anna Faris) has gone back to school and is pursuing her dream of becoming a lawyer, while Bonnie (Allison Janney) attempts to have a healthy romantic relationship with her boyfriend, Adam (William Fichtner), who was upgraded to series regular status for this season. Through it all, Christy and Bonnie rely on their support system from AA, including the wise Marjorie (Mimi Kennedy), the wealthy and sometimes misguided Jill (Jaime Pressly), and the overly emotional Wendy (Beth Hall). Collectively, they help each other stay sober in the face of whatever life throws at them. The episodes are usually titled with two odd topics that are mentioned in that episode. Season 4 marked the show's full revolution away from storylines involving Christy's children: daughter Violet (played by Sadie Calvano) only appeared in a handful of episodes, and son Roscoe (played by Blake Garrett Rosenthal) would make his final appearance ever on the show early on the season's run.

Season four of Mom aired Thursdays in the United States at 9:00 p.m. after The Great Indoors.
