The twenty-first season of the American police procedural television drama series NCIS was announced on February 21, 2023, by CBS, and premiered on February 12, 2024, and concluded on May 6, 2024. This is the first season not to feature David McCallum (as Dr. Donald "Ducky" Mallard), who died on September 25, 2023, though he is still posthumously credited in the first two episodes. Due to the 2023 Writers Guild of America and SAG-AFTRA strikes, the season consists of only 10 episodes, the smallest number in the show's history, shorter even than season 18, which was shortened due to the COVID-19 pandemic in the United States. This season also includes the 1,000th episode of the entire NCIS franchise, which aired on April 15. The previous season finale and this season's premiere episode were broadcast nine months apart, making it the longest break in the series's history.
On April 9, 2024, CBS renewed the show for a 22nd season.[1]
