season of television series

The eighteenth season of NCIS, an American police procedural drama television series, originally aired on CBS from November 17, 2020, through May 25, 2021. The season only contained 16 episodes, shortened due to the COVID-19 pandemic in the United States, making it the second shortest in the series behind season 21, and includes the series' 400th episode. This is the first season to not premiere in the usual September. The season was produced by Belisarius Productions and CBS Studios.

The series stars Mark Harmon, Sean Murray, Wilmer Valderrama, Emily Wickersham, Maria Bello, Brian Dietzen, Diona Reasonover, Rocky Carroll, and David McCallum. The season is Bello's last as a series regular, as she left after eight episodes. The season finale serves as Wickersham's final series regular appearance as Eleanor Bishop, leaving the series after 8 years. Several late-season episodes feature Pam Dawber, Harmon's real-life spouse.

Why this record matters
“NCIS season 18” is worth following because a concise public description often conceals a longer documentary argument. Here, NCIS, season and television provides the most credible route into that argument.
Object files, edition statements, performance records and contemporary criticism preserve different stages of the work’s history. The source revision retrieved here is dated Aug 28, 2026. The linked authority identifier is Q102112817. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2020 and 2021.
Rights, attribution and provenance may remain disputed even when a general reference summary presents a stable account. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
