CBS officially renewed NCIS for its 23rd season in February 2025, confirming it will be part of the 2025–2026 fall season en.wikipedia.org+15tvinsider.com+15paramountplus.com+15. While a firm date hasn’t been released yet, reliable industry outlets like TV Insider suggest that NCIS will return in late September or early October 2025, likely resuming its familiar Tuesday 8 PM ET/PT slot as part of a full “NCIS‑verse” night lineup tvinsider.com+1paramountplus.com+1.

Binder has teased an emotionally intense Season 23 focusing on Parker’s gripping quest for justice following his father’s death—a storyline that will unfold over the coming months during inevitable production in the summer people.com+3cinemablend.com+3tvinsider.com+3.
