NCIS: Tony & Ziva is an upcoming American television streaming series on Paramount+, serving as a spin-off of the long-running crime procedural NCIS. The series will star Michael Weatherly and Cote de Pablo reprising their roles as former NCIS special agents Anthony “Tony” DiNozzo and Ziva David, respectively, and will mark their first time appearing together in 12 years since NCIS season 11 episode “Past, Present and Future”.

The spin-off will reunite the two characters and center around the events that shaped their storyline in Europe. Weatherly was part of the original NCIS cast until his departure in 2016 but returned in 2024 for a special tribute episode honoring David McCallum, who portrayed Dr. Donald "Ducky" Mallard for 20 seasons, while de Pablo was a series regular from seasons 3 to 11 and made guest appearances in seasons 16 and 17.

It will be the seventh series set within the NCIS universe —also referred to as the "NCIS-verse"— and the first developed exclusively for a streaming platform. As of mid-April 2025, it was confirmed that the series will premiere in late 2025.

The showrunner for NCIS: Tony & Ziva described the project as "an unconventional love story." Both Weatherly and de Pablo will also serve as executive producers on the series, which they have reportedly been developing for several years. The storyline will open by revisiting and explaining the reasons behind the characters’ departure in the original series.

In mid-May 2024, the first official podcast of the NCIS universe, Off Duty: An NCIS Rewatch, premiered on Spotify. Hosted by Cote de Pablo and Michael Weatherly, the podcast revisits the show's most memorable episodes with behind-the-scenes commentary.
