Which NCIS should I watch first? The right starting point isn't called NCIS — and it's only two episodes long
Eight NCIS series, one shared universe, and a first episode that airs under a completely different show's title. Here's the entry point that makes the original premiere land properly, and the order everything else goes in after it.
NCIS premiered on September 23, 2003 with an episode called "Yankee White," and most people start there. They are starting on episode three.
The franchise 's actual first appearance is a two-part backdoor pilot embedded in JAG, CBS's Navy legal drama, which ran from 1995 to 2005. Season 8, episodes 20 and 21 — "Ice Queen," aired April 22, 2003, and "Meltdown," aired April 29, 2003 — introduce the team before CBS had even greenlit the spinoff.
What's actually in those two episodes
A pregnant Navy JAG officer, Lieutenant Loren Singer, turns up dead. NCIS Special Agent Leroy Jethro Gibbs takes the case and arrests Commander Harmon Rabb as his prime suspect, which is how the audience meets Gibbs: as an antagonist in someone else's show, arresting the hero. "Meltdown" delivers the real killer and Rabb's trial, with a terrorism subplot running underneath.
The cast is already almost assembled. Mark Harmon as Gibbs, Michael Weatherly as Tony DiNozzo, Pauley Perrette as Abby Sciuto, David McCallum as Ducky Mallard, Alan Dale as the NCIS director. The one seat that changes is the female field agent: Robyn Lively plays Vivian Blackadder here, and when the series launched, Sasha Alexander's Caitlin Todd took the slot.
"Ice Queen" pulled 13.8 million viewers and "Meltdown" 13.6 million, second that night only to American Idol. CBS ordered the series in May 2003.
Why it 's worth the 90 minutes
"Yankee White" opens with Gibbs and DiNozzo already functioning as a unit and a dynamic with Rabb that the pilot assumes you've seen. You haven't, unless you watched JAG. Two episodes fixes that, and you can skip the other 225 episodes of JAG without losing anything.
The order after that
- NCIS (2003– ) — the spine. Everything else branches off it.
- NCIS: Los Angeles (2009–2023) — introduced in the season 6 two-parter "Legend." Start it there.
- NCIS: New Orleans (2014– ) — seven seasons, introduced in the season 11 two-parter "Crescent City."
- NCIS: Hawai'i (2021–2024) — 54 episodes, no backdoor pilot, self-contained.
- NCIS: Sydney (2023– ) — the Australian series. Standalone; watch whenever.
- NCIS: Origins (2024– ) — the prequel, Gibbs at Camp Pendleton in 1991. Release order beats chronology here, because the payoffs depend on knowing where he ends up.
- NCIS: Tony & Ziva — Paramount+, picking up threads from NCIS season 17.
The one arriving this week
NCIS: New York premieres on CBS on October 6, 2026, built around LL Cool J's Sam Hanna, relocated from NCIS: Los Angeles by way of a recurring stint on NCIS: Hawai'i season 3. Scott Caan, Jennifer Beals, Jacqueline Byers, Shane Harper and Devin Druid fill out the field office. No two-parter this time — the franchise that invented the backdoor pilot gave this one a regular pilot and called it "Pilot."
Total runtime for the whole shared universe, if you're pricing it out: roughly 1,000 hours. The first 90 minutes are on the wrong show.
