or more than two decades, Navy CIS (NCIS) has dominated TV screens worldwide. With Season 23 currently running in the U.S., the franchise has expanded into a massive universe — six spin-offs, each exploring new locations, new agents, and new flavors of crime storytelling. But are they worth adding to your watchlist? Here’s a quick, sharp breakdown.
How This Ranking Works
Using IMDb user ratings, this list reflects overall audience reception across all NCIS spin-offs. Some shows are long concluded, others still going strong — but each has left a mark on the NCIS brand.
Rank 6 — NCIS: Sydney (IMDb 6.2)
The newest global branch of the franchise, NCIS: Sydney launched in 2021 and made history as the first NCIS series produced outside the U.S. Teaming up with the Australian Federal Police, this squad faces wildlife smuggling rings, high-tech maritime threats, and sun-drenched chaos in the Pacific.
Season 3 arrives in October 2025, with streaming available on Paramount+ and Waipu.tv.
Rank 5 — NCIS: Los Angeles (IMDb 6.8)
The very first spin-off, NCIS: L.A. set the tone for the franchise’s expansion. From 2009 to 2023, fans followed Callen, Sam Hanna, and a lively cast of agents handling West Coast naval crime — plus plenty of personal drama.
A classic procedural with big action and bigger personalities, it’s still streaming widely, including on Joyn for free.
