NCIS began launching spinoffs in 2009 when it first introduced the cast of NCIS: Los Angeles, but the franchise tradition dates back even further than that. NCIS started as a spinoff of the ’90s military legal procedural JAG, with a two-part special in 2003 serving as the backdoor pilot. The highly successful offshoot made it a no-brainer for the network to explore expanding the franchise even further. With two more series coming to CBS and Paramount+, it’s worth looking at everything that makes each NCIS series stand out against the rest.
The best NCIS episodes from each of the show’s 21 seasons pushed memorable characters like Leroy Jethro Gibbs and Tony DiNozzo to their limits.

NCIS premiered in 2003 and is currently airing
NCIS was launched in JAG season 8, episode 20, “Ice Queen,” and episode 21, “Meltdown.” The episodes introduced Mark Harmon as Leroy Jethro Gibbs, Pauley Perrette as Abby Sciuto, David McCallum as Donald Mallard, and Michael Weatherly as Anthony DiNozzo. NCIS has since aired for over two decades, with compelling stories expected in season 22 after the shocking events in the season 21 finale. NCIS season 22 will feature McGee and Jimmy, whose actors Sean Murray and Brian Dietzen have been with the show since season 1.

7NCIS: Los Angeles
NCIS: Los Angeles premiered in 2009 and ran until 2023
The series introduced beloved characters to the franchise: G. Callen (Chris O’Donnell), Sam Hanna (LL Cool J), Special Agent Kensi Blye (Daniela Ruah), and LAPD-NCIS Liaison Officer Marty Deeks (Eric Christian Olsen). Kensi and Deeks had many memorable episodes as the pair had one of the most charming relationships in the franchise. Viewers even witnessed the pair tying the knot in NCIS: Los Angeles season 10, episode 17, “Till Death Do Us Part.” It was pivotal for NCIS to allow the lead characters to act on their romantic feelings. The Los Angeles-based series was canceled in 2023 after 14 seasons.

6NCIS: Red
NCIS: Red’s backdoor pilot aired on NCIS: Los Angeles in 2013
Following the development of NCIS: Los Angeles, the series attempted to launch a spinoff that never got off the ground. NCIS: Red was a backdoor pilot that aired on NCIS: Los Angeles in 2013, four years after the California-based spinoff premiered. The NCIS: Red team was introduced in NCIS: Los Angeles season 4, episode 18, “Red,” and episode 19, “Red-2.” The NCIS Red Team is one of several mobile NCIS units designated by color. The series would have featured John Corbett as former Special Agent Roy Haines in the shared NCIS universe.
CBS opted not to pick up NCIS: Red as its own series and would introduce NCIS: New Orleans the following year. Had the series been picked up, it would have marked the dawn of exciting beginnings for the franchise. Special Agent in Charge of the NCIS Red Team Paris Summerskill (Kim Raver) would have been the first female lead of an NCIS team depicted in the series. (The honor now belongs to Vanessa Lachey of NCIS: Hawai’i.) It also would have marked the franchise’s first fourth-generation spinoff.
5NCIS: New Orleans
NCIS: New Orleans premiered in 2014 and ran until 2021
The show had a pretty good run, airing for seven seasons on CBS and featuring many memorable guest stars on NCIS: New Orleans. Despite introducing fan-favorite characters, NCIS: New Orleans aired its final episode in 2021, making it the first successful spinoff in the NCIS franchise to come to an end. The series introduced characters that could return to the franchise, including a promising NCIS spinoff character, Gregorio, who could replace Jessica Knight in the main series.

4NCIS: Hawai’i
NCIS: Hawai’i premiered in 2021 and ran until 2024
The introduction of the island-based spinoff marked the NCIS franchise departing from its trend of the flagship series launching spinoffs with backdoor pilots. In 2021, NCIS: Hawai’i premiered on CBS with a cold launch. In 2024, after the announcement that the franchise would be pursuing two new spinoffs based on the original NCIS cast members, CBS made the controversial announcement that NCIS: Hawai’i would not return for season 4. NCIS: Hawai’i’s cancelation marked a massive loss for the NCIS franchise, forgoing the positive representation of lead female characters for other endeavors.

3NCIS: Sydney
NCIS: Sydney premiered in 2023 and is currently airing
Other characters include NCIS Special Agent DeShawn Jackson (Sean Sagar), AFP liaison officer Constable Evie Cooper (Tuuli Narkle), ex-Austrailian Navy Medic Roy Penrose (William McInnes), and Bluebird “Blue” Gleeson as the team’s forensic scientist. The characters experience a more connected storyline in the Sydney-based series, following a central threat narrative throughout the show. NCIS: Sydney also broke from the NCIS backdoor pilot trend, with the characters introducing themselves on their show when it debuted in 2023. The story will continue for the Aussie-based characters, as NCIS: Sydney was renewed for season 2.

2NCIS: Tony & Ziva
Production on NCIS: Tony & Ziva will begin in summer 2024
The spinoff could fix a big problem with Tony and Ziva’s NCIS romance with a more streamlined narrative centered on the two characters. While Cote de Pablo returned to NCIS in season 17, the couple had not personally revealed the status of their family on the small screen. When Tony and Ziva were last heard from on the flagship series, they lived in Paris with their daughter, Tali David-DiNozzo. That said, the couple’s reunion was never shown on TV, giving viewers much to look forward to when the show streams.
1NCIS: Origins
NCIS: Origins will premiere in September 2024
While it has a similar focus on the main characters from the flagship, NCIS: Origins is taking a major risk that NCIS: Tony & Ziva isn’t. Rather than Mark Harmon’s son, Sean Harmon, returning to the role, Austin Stowell was cast as young Gibbs. It will be crucial that the actor offers audiences a performance that strikes the right blend of how Gibbs would have acted after his time in the Marine Corps and before his time at NCIS Headquarters to give viewers a fluid experience. While Mark Harmon will not return as Gibbs, he will narrate the series.
