If you're trying to figure out how many NCIS shows exist, you aren't alone. What started as a backdoor pilot on the legal drama JAG has expanded into a massive television universe spanning over two decades. Today, the franchise consists of eight distinct television series, crossing multiple cities, international waters, and streaming platforms.
Understanding this expanding lineup helps whether you're a longtime fan catching up on every spin-off or a newcomer trying to figure out where to begin. Here is the complete breakdown of every series in the franchise, how they connect, and what makes each one unique.
The Core Lineup: Every NCIS Series Explained
The franchise has grown far beyond its Washington, D.C. roots. To grasp the full scope, it helps to look at each series in the order they entered the television landscape.
1. NCIS (2003–Present)
The flagship series that started it all follows the Major Case Response Team (MCRT) of the Naval Criminal Investigative Service, headquartered in the Washington Navy Yard. Led for its first eighteen seasons by Leroy Jethro Gibbs (played by Mark Harmon) and later by agents like Alden Parker (Gary Cole), the show blends military-focused crime-solving with deep character ensemble dynamics. It remains a cornerstone of the CBS primetime schedule.
2. NCIS: Los Angeles (2009–2023)
As the first official spin-off, this series shifted the formula toward high-octane undercover operations and sleek tech. Operating out of the Office of Special Projects (OSP), agents like G. Callen (Chris O'Donnell) and Sam Hanna (LL Cool J) handled national security threats on the West Coast. It ran for 14 seasons before wrapping up its run.
3. NCIS: New Orleans (2014–2021)
Set against the distinct cultural backdrop of the Louisiana bayou, this iteration was led by Dwayne Pride (Scott Bakula). The show leaned heavily into local music, food, and regional crime dynamics while maintaining the military procedural structure fans expected. It concluded after seven seasons.
4. NCIS: Hawaiʻi (2021–2024)
Breaking ground as the first series in the franchise to feature a female lead, this installment followed Special Agent Jane Tennant (Vanessa Lachey) managing naval crimes and island jurisdiction across the Hawaiian islands. It ran for three seasons before its cancellation.
5. NCIS: Sydney (2023–Present)
The franchise went international with this co-production, set against the backdrop of the Australian Federal Police and NCIS agents working jointly in the Indo-Pacific region. It brings a distinct international flavor and unique jurisdictional friction to the standard formula.
6. NCIS: Origins (2024–Present)
This prequel series steps back in time to explore the early days of Leroy Jethro Gibbs as a newly minted special agent at the Camp Pendleton NIS office in the early 1990s. It offers a grittier, character-driven look at the trauma and experiences that shaped the iconic leader.
7. NCIS: Tony & Ziva (2025)
Moving away from traditional network television formatting, this streaming-exclusive series launched on Paramount+. It reunited fan-favorite characters Tony DiNozzo and Ziva David on the run across Europe as they tried to uncover a conspiracy while navigating life as parents.
8. NCIS: New York (2026–Present)
Expanding the universe further, this installment brought LL Cool J's Sam Hanna back into a regular starring role alongside new faces in New York City, blending fast-paced metropolitan investigations with the familiar military oversight framework.
The Connection to JAG
Many viewers stumble upon JAG while looking for the complete watch order. While JAG (Judge Advocate General) is technically a separate legal drama that aired from 1995 to 2005, its eighth season featured a two-part backdoor pilot explicitly designed to introduce the characters of the Naval Criminal Investigative Service. You don't need to watch all ten seasons of JAG to understand the franchise, but those specific episodes serve as the unofficial ground zero for the universe.
Common Misconceptions About the Franchise
When diving into a massive television universe, myths often circulate online about what counts and what doesn't.
- Thinking every spin-off is still on the air: Several entries, including Los Angeles, New Orleans, and Hawaiʻi, have concluded. Only a select few active series receive new episodes concurrently.
- Assuming you must watch every show in order: Unlike serialized sci-fi universes, most NCIS series are procedural. While character crossovers happen, you can easily enjoy individual spin-offs without memorizing every plot point from the others.
- Confusing network and streaming rules: Traditional entries air on broadcast television with standard 20+ episode seasonal runs, whereas streaming offshoots like Tony & Ziva use shorter, serialized formats.
Frequently Asked Questions
Do I need to watch the shows in chronological order?
No. Because most entries are standalone investigative procedurals, you can pick up almost any series—like NCIS: Sydney or the flagship show—without watching the previous spin-offs. Chronological order matters more if you want to catch subtle crossover references and character progression.
Which NCIS show has the most seasons?
The flagship NCIS series holds the record by a wide margin, stretching across more than two decades and over twenty-four seasons.
Are all the shows set in the same fictional universe?
Yes. Every official series exists within the same continuity, allowing for occasional crossover events, shared character appearances, and crossover references between domestic and international branches.
Where can I stream all the NCIS series?
Availability varies by region, but in the United States, the flagship series and its domestic spin-offs are primarily housed on streaming platforms like Paramount+, alongside network-specific digital apps.
