The eighteenth season of NCIS, an American police procedural drama television series, originally aired on CBS from November 17, 2020 through May 25, 2021.[1] The season only contained 16 episodes,[2] making it the second shortest in the series behind season 21, and includes the series' 400th episode. The season was produced by Belisarius Productions and CBS Studios.[3]
NCIS revolves around a fictional team of special agents from the Naval Criminal Investigative Service, which conducts criminal investigations involving the U.S. Navy and Marine Corps. 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.[4] The season finale serves as Wickersham's final appearance as Eleanor Bishop, leaving the series after 8 years.[5] Several late-season episodes feature Pam Dawber, Harmon's real-life spouse.
