One of TV’s most popular franchises is going to continue to be a hit for CBS. CBS already has 16 shows set for its 2026-2027 season, and among them are the NCIS shows. This year, the three — NCIS, NCIS: Origins, and NCIS: Sydney — air back-to-back-to-back on Tuesday nights. Read on for everything we know so far about an NCIS: Sydney Season 4, from the cast to a premiere date and more. Is NCIS: Sydney renewed for Season 4? Yes, it was one of 10 series that CBS renewed in January for the 2026-2027 season. When will NCIS: Sydney Season 4 premiere? It’s too soon to know. That won’t be announced until after Season 3 finishes airing.
