NCIS: Los Angeles received generally mixed-to-positive reviews from critics, but became a solid ratings hit for CBS at the time of its premiere. The series received sixTeen Choice Awards for Choice Action Show, Choice TV Actress Action for Hunt, and Choice TV Actor Action for LL Cool J.

NCIS: Los Angeles followsSpecial Agents Sam Hanna (LL Cool J) and Grisha Callen (Chris O'Donnell),undercover agents assigned to theOffice of Special Projects, a special branch of theNaval Criminal Investigative Service that specializes inundercover assignments. Sam is an ex-US Navy SEAL and former member ofSEAL Team Six and dedicated family man. Callen is a former foster child who became a "legend" under the watchful eye of Operations Manager Henrietta "Hetty" Lange (Linda Hunt). At the start of the series, Sam, Callen, and Hetty are supported by Special Agent Kensi Blye (Daniela Ruah), a hand-to-hand combat specialist, trained sniper and forensic whiz, rookie agent Dominic Vail (Adam Jamal Craig), Operational Psychologist Nate Getz (Peter Cambor) and Technical Operator Eric Beale (Barrett Foa). Vail is abducted by terrorists halfway through season 1 and, following a period of being held hostage, is killed during his rescue mission near the end of the season. Getz, meanwhile, enters training to become an agent in the back-half of the season, and is reassigned during season 2, returning for occasional guest appearances afterwards.

In season 2,LAPD Detective Marty Deeks (Eric Christian Olsen), after helping on several cases late in the prior season, joins the OSP team as a liaison between LAPD and NCIS, replacing Vail as Kensi's partner. He holds this position until departmental reforms in season 12 end up terminating it, after which he completesFLETC training and officially joins NCIS as anInvestigator. Over the course of the series, Deeks and Kensi slowly evolve from partners to lovers, with the two marrying in season 10. The two then become foster parents to immigrant teenager Rosa in season 13 and are revealed to be expecting their own baby in the series finale. Also joining the team in season 2 is Intelligence Analyst Nell Jones (Renee Felice Smith), a brilliant agent whom Hetty hopes to have take her place eventually, and who forms a close relationship with Beale.

During season 3, Assistant Director Owen Granger (Miguel Ferrer), an old friend of Hetty's, is assigned to the team as oversight with her, and manages to develop a cordial relationship with the team despite a frosty start. In season 8, Granger falls ill with cancer, coinciding with Ferrer's real-life battle with the disease; following Ferrer's death, Granger is written to have fled the hospital while in recovery from a failed assassination attempt, and is later confirmed to have died from his illness during the following season.

In season 9, Executive Assistant Director Pacific (EADPAC) Shay Mosley (Nia Long) is assigned to the OSP after Hetty leaves on a personal mission to free an old colleague in Vietnam; the team later rescues her when the mission goes wrong. Mosley, meanwhile, sends the team on an unsanctioned mission to Mexico to rescue her son from her criminal ex-husband at the end of the season; while successful in its goals, the mission results in the death of Mosley's trusted assistant, the wounding of most of the rest of team, and the OSP being put under the microscope during the beginning of season 10; Mosley later accepts full responsibility, resigns and goes into hiding with her son to escape a cartel allied with her ex (whom she had killed during the mission).

During seasons 11 and 12, rookie agents Fatima Nazami (Medalion Rahimi) and Devin Rountree (Caleb Castille) are recruited to the OSP, while Beale and Jones depart for the private sector at the end of the latter season. With Hetty leaving to do damage control from a prior mission, Admiral Hollace Kilbride (Gerald McRaney), who has assisted the OSP in multiple cases, is assigned in her place as Director of Special Operations in season 13. The series ends with Callen marrying long-time love Anna Kolcheck, and him and Sam taking a "side project" mission to find and rescue Hetty with a new team, which includes old teammates Nate and Nell.

In November 2008, it was reported that a firstNCIS spin-off series set in Los Angeles would be introduced with a two-part backdoor pilot during thesixth season ofNCIS.^[15][16] Special Agent G. Callen was initially a CIA operative created by Shane Brennan for a series that was never produced. After taking over show runner duties previously held byDonald P. Bellisario onNCIS, he used the potential of a spin-off to bring his story to fruition.

Brennan intended for the series to hold aMiami Vice-esque vibe through its two co-leads, Callen and Agent Sam Hanna. However, the character of Lara Macy was written to serve as a parallel for Gibbs, the lead of the original NCIS team. Macy was portrayed byLouise Lombard in the backdoor pilot, but she was not featured in the actual spin-off, and Brennan was able to produce the show as he originally envisioned it.

The show was known asNCIS: Legend while in production (referring to the episodes ofNCIS in which the spin-off was introduced), and other names considered includedOSP: Office of Special Projects,NCIS: OSP andNCIS: Undercover.^[17] Filming started in February 2009, with the characters being introduced in the two-partNCIS episode titled "Legend", the first part of which aired on April 28, 2009.^[17][18] This episode served as abackdoor pilot for the series, in a manner similar to the wayNCIS was introduced by way of a two-part episode ofJAG.

In May 2009, CBS picked up the series.^{[19][20][21][17]}

On January 20, 2023, it was announced that the series would end after the fourteenth season, with the series finale airing on May 21, 2023.^[22]

In April 2011,NCIS creator Donald Bellisario sued CBS overNCIS: Los Angeles because of his contract which gave him "first opportunity" to develop a spin-off or sequel;^[23] the lawsuit was dismissed by a judge in June 2012. However, discussions continued between CBS and Bellisario, and in January 2013 the dispute was settled outside of court a week before it was set to go to trial; the terms of the agreement were not disclosed but were described as being amicable.^[24][25][26]

The series premiered in the United States onCBS on September 22, 2009. In Canada, the series aired onGlobal like its sister series. In Asia, the series airs onAXN,AXN, and TVOne Pakistan.^[27] In the UK the series premieres its latest season first on Sky 1, with subsequent runs and repeats then also broadcast onChannel 5.^[28] In the Netherlands the series airs on NET5.NCIS: Los Angeles airs onNetwork 10,10 Bold,Paramount+ andTVH!TS (formerlyTV1).

The first season DVD release includes the two-partpilot episode that aired as part of the sixth season ofNCIS, which were also included on the Season 6 DVD ofNCIS. All releases are distributed byParamount Home Entertainment.

"Identity", the series' first episode, garnered 18.73 million viewers with a 4.4/11 share in the 18- to 49-year-old demographic and therefore won its timeslot. It was the second-most-watched show of the week, behind only the originalNCIS.^[30]

Reviews for the show have been mixed. It has a score of 59/100 onMetacritic. According to Mary McNamara of theLos Angeles Times, "The crime is intriguing and multifaceted, its resolution requiring a nice balance of street smarts and lots of gunfire. But as with the original 'NCIS', the emphasis is on the characters of the team... Los Angeles, meanwhile, looks fabulous, a pleasing mixture of noir and gridlock, and there's an air of stability that's comforting in these uncertain times."^[31] The New YorkDaily News reviewer, David Hinckley, was more critical of the show saying that although "It all adds up to an hour of decent entertainment, and there's room for enough character development to give 'NCIS: Los Angeles' a personality of its own, ... a premiere episode shouldn't feel even a little like something we've already seen."^[32]

Tom Shales ofThe Washington Post felt that, "NCIS: Los Angeles gets the job done ... It's a procedural that follows strictly the established procedure, but it has likable characters, dislikable bad guys and the occasional flabbergasting shot of L.A."^[33] Robert Bianco ofUSA Today summarized it as a "serviceable hour that takes the NCIS formula—a light tone and a lot of banter wrapped around a fairly rudimentary investigatory plot—and transfers it to a special, undercover NCIS division in Los Angeles. Nothing more, but also nothing less."^[34]The Hollywood Reporter compared the show toThe A-Team with "the same lighthearted approach to life-or-death situations. Maybe the biggest change is that 'NCIS: L.A.' achieves its inevitably favorable outcomes with a little more intellect and a little less testosterone."^[35]IGN stated that although "NCIS: Los Angeles doesn't exactly reinvent the police procedural... it's another above-average entry, aided by the fact that the people behind the show know what they're doing" and ultimately gave the episode a 7.7/10.^[36] On the website ofIMDb, the series has a score of 6,8/10 on 57 000 critics.^[37]
