Marvel's Inhumans, or simply Inhumans, is an American television series created by Scott Buck for ABC based on the Marvel Comics race of the same name. It is set in the Marvel Cinematic Universe (MCU) and acknowledges the franchise's other television series. It was produced by ABC Studios and Marvel Television in association with Devilina Productions, and was co-financed by IMAX Entertainment in a deal that gave the series a theatrical premiere. Buck served as showrunner on the series.

The series is centered on Black Bolt, portrayed by Anson Mount, and other members of the Inhuman Royal Family. Serinda Swan, Ken Leung, Eme Ikwuakor, Isabelle Cornish, Ellen Woglom, and Iwan Rheon also star. Marvel Studios announced an Inhumans film in 2014 as part of their Phase Three slate of films, with the species first introduced to the MCU in the series Agents of S.H.I.E.L.D. The film was removed from Marvel Studios' slate in April 2016, and the Inhumans series was announced that November, to be partly filmed using IMAX cameras. Buck joined the series in October, and Mount was cast in February 2017. Filming took place from March to June 2017, at the former Naval Air Station Barbers Point airfield in Kalaeloa, Hawaii and various locations on the island of Oahu.

Inhumans debuted on IMAX screens on September 1, 2017, the first live-action television series to do so. The theatrical run lasted two weeks, before the series premiered on ABC on September 29 and ran for eight episodes, concluding on November 10. The series was met with unfavorable reviews and low television ratings, and was canceled by ABC in May 2018. Mount reprised his role as an alternate version of Black Bolt in Marvel Studios' MCU film Doctor Strange in the Multiverse of Madness (2022).

After a military coup, the Inhuman Royal Family escape to Hawaii, where they must save themselves and the world.

Crystal's 2,000-pound (910 kg) teleporting canine companion Lockjaw also appears in the series, created through CGI. Reiné stated that "nobody has done a full CG character on a TV series before. So Lockjaw is the first. It's a big responsibility for all of us." Mount called Lockjaw the "goofy sidekick" but felt that he had been integrated into the plot rather than just used as comic relief. Buck felt Lockjaw's storylines would "always [be] fairly simple" as a way to ensure the writers "don't try to pretend that he's anything other than" a dog and pull focus from the other characters. Initial designs for Lockjaw had him bigger than his final look, closer to "the size of a Mini Cooper".

A film based on the Inhumans was first mentioned as being in development in a March 2011 trade report. In October 2014, Marvel Studios officially announced the film as part of the Marvel Cinematic Universe's Phase Three, with a release date of November 2, 2018. Producer Kevin Feige said, "We really do believe the Inhumans can be a franchise or a series of franchises unto themselves. They have dozens of powers and an amazing social structure. With our 20th movie in the Marvel Cinematic Universe, we wanted to continue to refine what that universe is about." The following December, the Inhuman species was introduced during the second season of Marvel's Agents of S.H.I.E.L.D., which began a storyline that recurred throughout the series moving forward. In April 2016, the film was officially taken off of Marvel's release schedule, though it was not outright canceled. After the film's cancellation, Jed Whedon, executive producer and showrunner on Agents of S.H.I.E.L.D., noted that series had "a little more freedom" and were "able to do a little bit more" with the species going into the fourth season, including the potential of introducing some of the "classic" Inhumans.

In May 2016, after ABC had canceled Marvel's Agent Carter and passed on Marvel's Most Wanted, ABC Entertainment president Channing Dungey said that Marvel and ABC were looking "at series that would be beneficial to both brands" moving forward. In November, Feige said that "Inhumans will happen for sure. I don't know when. I think it's happening on television. And I think as we get into Phase 4 as I've always said, it could happen as a movie." Shortly after, Marvel Television and IMAX Corporation announced the eight-episode television series Inhumans, to be produced in conjunction with ABC Studios and air on ABC; Marvel Studios decided that the characters were better suited to television, and a series would be better than trying to fit the multiple planned franchise films around the studio's existing film franchises. Inhumans was not intended to be a reworking of the planned film, nor a spin-off from Agents of S.H.I.E.L.D., but it is set in the same shared universe. In December, Scott Buck, the showrunner for the first season of the Marvel Netflix series Iron Fist, was revealed to also be executive producing and showrunning Inhumans. Jeph Loeb and Jim Chory also executive produce the series.

IMAX serves as a financing partner on the series, the first time it had done so for a television series, paying completely for the first two episodes. IMAX had originally approached Marvel about the deal after a successful IMAX event with Game of Thrones in 2015. Because of this deal, Marvel was able to spend more on Inhumans than it has on its other shows, especially for visual effects, which have been criticized in series like Agents of S.H.I.E.L.D. ABC also hoped that partnering with IMAX would attract a larger audience to the series than its previous Marvel shows, similar to the "buzz-creating, widely watched series" that Marvel provides to Netflix, and perhaps even draw more viewers to Agents of S.H.I.E.L.D.'s fifth season in the 2017–18 television season. Ben Sherwood, president of Disney–ABC Television Group, described the deal as "a quadruple win—a win for IMAX, a win for Marvel, a win for ABC Studios and a win for ABC to launch a show in an innovative way and get attention" in an increasingly crowded market for original television series. Buck felt working with IMAX "gave us a lot more freedom and pushed and encouraged us to think a little bit bigger than we would if it was just a normal network show. We just wanted to think bigger in terms of scope, and what we were seeing, and how we bring these characters to the audience." Loeb cautioned that Inhumans was "a television show that is premiering in an IMAX theater" rather than a film, but that it would still be a spectacle, and "a unique way to be able to see TV".
