Status for season 9
The series is NOT renewed for a new season. It has been cancelled and there will not be a season 9
CBS has announced that "Mom" is cancelled with no season 9: the series will be over at the end of the current eighth season with a series finale scheduled on Thursday, May 13th 2021, at 9/8c.
Mom‘s season 8 marked the first season without series co-lead Anna Faris, who played Christy. This was perhaps an early signal that the series was losing steam, despite still very high ratings.
From hit-maker Chuck Lorre comes his next big comedy‐an irreverent and outrageous take on true family love‐and dysfunction.
Newly sober single mom Christy struggles to raise two children in a world full of temptations and pitfalls. Testing her sobriety is her formerly estranged mother, now back in Christy's life and eager to share passive-aggressive insights into her daughter's many mistakes.
