Loki is an American television series based on the Marvel Comics superhero of the same name, developed by Michael Waldron for the Disney+ streaming service. Waldron is the show's lead writer, and Kate Herron is the first season's director.

An alternate version of Loki is transported to the mysterious Time Variance Authority (TVA), a bureaucratic agency that exists outside of time and space that oversees the chronology. They offer Loki the choice of being eliminated from existence as a "time variant" or assisting in the timeline repair and preventing a greater threat. Loki becomes entrapped in his own time-traveling crime thriller.

Gugu Mbatha-Raw, Wunmi Mosaku, Eugene Cordero, Tara Strong, Owen Wilson, Sophia Di Martino, Sasha Lane, Jack Veal, DeObia Oparei, Richard E. Grant, and Jonathan Majors also star, with Tom Hiddleston reprising his role as Loki from the film series. Filming began in Atlanta, Georgia, in February 2020, but was put on hold in March 2020 owing to the COVID-19 pandemic. In September of that year, production resumed and was completed in December.

Loki made its debut on June 9, 2021. Its debut season, which lasted six episodes, ended on July 14 and is part of the MCU's Phase Four. It was well-received, with compliments on the performances, musical score, and visuals. A second season is now in the works.
