''Agents of S.H.I.E.L.D.'' (or ''[[InCaseYouForgotWhoWroteIt Marvel's]] Agents of S.H.I.E.L.D.'') is a TV series set in the Franchise/MarvelCinematicUniverse, focusing on the organization ComicBook/{{SHIELD}} and taking place after ''Film/{{The Avengers|2012}}'' and ''Film/IronMan3'' chronologically. Premiering in September 2013 on Creator/{{ABC}}, it was created and executive produced by Creator/JossWhedon, [[ProductionPosse Jed Whedon and Maurissa Tancharoen]] (Joss Whedon also directed the pilot). It stars Creator/MingNaWen, Creator/ElizabethHenstridge, Creator/IainDeCaestecker, Creator/BrettDalton, Creator/ChloeBennet, and Creator/ClarkGregg as [[BackFromTheDead a very much alive]] Agent Phil Coulson, with later additions Creator/AdriannePalicki, Creator/NickBlood, Creator/HenrySimmons, and Creator/LukeMitchell joining the main cast after its inaugural season.

The series began with the agents investigating and containing various supernatural and high-tech objects and individuals in order to keep the public safe, a task that has become more complicated in the aftermath of the Battle of New York [[TheUnmasquedWorld blowing the lid off of their previous level of secrecy]]. The status quo was upended midway through the first season, when [[Film/CaptainAmericaTheWinterSoldier S.H.I.E.L.D. was dissolved after it was compromised by the terrorist group HYDRA.]] The series now follows Coulson as his team struggles to rebuild the organization from its remaining loyal elements, even as they are being hunted by the U.S. Army, HYDRA, and other hostile forces of the Franchise/MarvelCinematicUniverse.

While the previous Marvel Cinematic Universe films focused on Creator/MarvelComics characters who already existed in the comics themselves, ''Agents of S.H.I.E.L.D.'' focuses primarily on characters original to the MCU, though there have been an increasing number of crossovers with comic and MCU characters, and several episodes have been direct follow-ups to the films. The reciprocity goes both ways, with events in the series seriously impacting the rest of the Franchise/MarvelCinematicUniverse, while a [[ComicBook/SHIELD2014 comic book series with the Marvel 616 versions of the team]] ran from December 2014 to November 2015; [[ComicBook/AgentsOfSHIELD a second one (bearing the same title as the show)]] launched as part of the ComicBook/AllNewAllDifferentMarvel initiative in January 2016.

A spinoff involving Lance Hunter and Mockingbird titled ''Marvel's Most Wanted'' was announced in April 2015 and later seemingly put on the backburner in favor of renewing ''Agents'' for a third season, and ''Series/AgentCarter'' for a second season. ''Marvel's Most Wanted'' was cancelled officially alongside ''Agent Carter'' in May 2016. During December 2016, Marvel released a six-episode web series, ''WebVideo/AgentsOfSHIELDSlingshot'', starring Creator/NataliaCordovaBuckley as Elena "Yo-Yo" Rodriguez.

A sixth season was officially confirmed in May 2018, with plans for a reduced 13-episode run put into place instead of the usual 22.
