An anthology series is a written series, radio, television, film, or video game series that presents a different story and a different set of characters in each different episode, season, segment, or short. These usually have a different cast in each episode, but several series in the past, such as Four Star Playhouse, employed a permanent troupe of character actors who would appear in a different drama each week. Some anthology series, such as Studio One, began on radio and then expanded to television.

True Detective is an American anthology crime drama television series created by Nic Pizzolatto. The series, broadcast by the premium cable network HBO in the United States, premiered on January 12, 2014. Each season of the series is structured as a self-contained narrative, employing new cast ensembles, and following various sets of characters and settings.
