This is a list of television series canceled before airing an episode. While many television shows are produced as pilots that never air on television or in any medium, the scope of this article is to list shows that were officially announced to be broadcast, but then canceled prior to the scheduled debut on the original network. Shows are listed in alphabetical order with the slated year of debut (plus timeframe or specific premiere date where applicable), known cast and plot information, the reason for cancellation (if known), and what happened to the series after cancellation.

; ''The Activist'' (October 22, 2021)
:Created by Global Citizen and Live Nation, this reality competition show, hosted by Usher, Priyanka Chopra and Julianne Hough, was to focus on six activists working to bring meaningful change to one of three urgent causes: health, education, and the environment, with the finalists attending the 2021 G20 summit to raise funds for their cause and the one raising the most funds being crowned "The Activist". The way the contestants' success would have been judged, which was by social media engagement and assessments by the hosts, drew immense backlash. Originally slated for an October premiere date on CBS for the 2021-22 season, the show was reportedly reformatted to a documentary special following the controversy although it is unknown if this has ever been aired.

; ''All My Babies' Mamas'' (early 2013)

''All-Star Celebrity Bowling'' was one of at least three shows canceled in this manner.

; ''Amazon High'' (1997)
: Selma Blair starred as a present-day orphaned high school student who accidentally travels back in time to the mythical days of the Amazons.

Later, portions of the pilot were adapted and edited into the '' Xena: Warrior Princess'' episode "Lifeblood" in 2000.

; '' American Princess'' (2003)
:American reality show produced by NBC in 2003. It involved 20 American women who are average, plain, and rather ill-mannered, being taken to London to master the finer arts of British society and be crowned "American Princess" and earn valuable prizes. The series was set as a midseason replacement sometime in the 2003–04 season, but never made it to air. Two years later, the series was finally run on WE tv, where it was a success and later picked up for another season, before ultimately ending in 2007.

; ''Angels '88/'89'' (1988 & 1989)
:Attempted revival of ''Charlie's Angels'' that was proposed for the then-new Fox network produced by Aaron Spelling in the wake of the 1988 Writers Guild of America strike, allowing the re-use of scripts from the original series without the need for writers. Four women (including Téa Leoni) were selected to star. It was renamed ''Angels 89'' due to production delays taking it into the following calendar year. It was eventually abandoned the next year after the settlement of the writer's strike.

:A dark drama series based on the Israeli series ''Nevelot'' starring Richard Gere that was given a straight-to-series order in late 2018 by Apple TV+. It was said to focus on two Vietnam veterans and best friends, and would have been Gere's highest-profile TV role. Howard Gordon and Warren Leight collaborated on two scripts for ''Bastards'', but Apple was concerned about the "show's tone of vigilante justice" and scrapped the show. A previous attempt at an American adaptation of ''Nevelot'' was in development at HBO in 2015 before it was eventually scrapped.

; ''The Big D'' (July 7, 2022)
:An American reality dating competition show that was scheduled to air on TBS, hosted by JoJo Fletcher and Jordan Rodgers.

The series was eventually picked up by the USA Network and aired in 2023.

; ''Bill and Martha'' (fall 1964)
:An American situational comedy starring William Bendix and Martha Raye that was scheduled to air on CBS, but was not aired due to the purported shaky health of Bendix.

The case was settled out of court for an undisclosed amount and Bendix subsequently died on December 14, 1964, from complications of stomach cancer and pneumonia.

; ''Bimbos et Intellos'' (2007)

; '' Blonde Charity Mafia'' (July 7, 2009, early 2010)
:An American reality series developed by Lifetime, it followed three Washington, D.C. socialites whose lives revolved around charity events. After production was completed on one six-episode season, Lifetime decided to sell the show to The CW network rather than air it itself. The CW scheduled the July premiere date for the series, but later decided to forgo all original programming for that Summer and programed the show as a midseason replacement for the 2009–10 season. Sometime after that decision, the network apparently lost interest in the series; references to it were removed from CW websites, and on December 29 the network officially confirmed that it would not air the show at all. It was apparently dropped in favor of two other reality series developed by The CW, '' Fly Girls'' and ''High Society''. The series did air on MTV Australia and MTV New Zealand in August and September 2009.

; ''Bridge & Tunnel'' (2010)
:MTV documentary reality show following the lives of young residents on Staten Island. The show was in production and had a scheduled air date for October 2010 but was ultimately pulled for being too similar to the network's hit ''Jersey Shore'' despite being slice of life documentary-style in comparison to ''Jersey Shore''s show-set residence. The concept of a Staten Island-based reality program was revisited by MTV at the start of 2019 with '' Made in Staten Island''. However, that project would air only three episodes on the network in January 2019 before being pulled due to low ratings and general criticism of a focus on younger people in the show with possible organized crime/mob ties, which MTV exploited with a ''Sopranos''-inspired launch campaign; some of that cast would be involved in another series, '' Families of the Mafia'', meant to take a less confrontational view of Mob families in general; that series would air all six of its episodes in the spring of 2020.

C

; ''Coastocoast'' (September 14, 1978)
:This hour-long sitcom about two airline stewardesses from Bud Yorkin's production company was originally announced for NBC's Thursday night schedule.

; ''Commando Nanny'' (September 17, 2004)
:A sitcom series for The WB, created by ''Survivor'' producer Mark Burnett, was based on his life as an au pair (he is also a former squaddie, serving in No3 Para).

; ''Confederate'' (2020)
:''Confederate'' was a planned, but never made, American alternate history drama television series developed for the network HBO by David Benioff and D. B. Weiss, who had previously developed the HBO series ''Game of Thrones''. The series was to be set in a timeline where the American Civil War ended in a stalemate. The announcement was followed by anger and criticism on social media with some describing it as slavery fan fiction, leading to the hashtag #NoConfederate, which trended number one in the United States and number two worldwide on Twitter in mid 2017. In April 2018, ''Variety'' reported the future of ''Confederate'' is uncertain. In July 2018, HBO president Casey Bloys confirmed the series was still in development, and hoped it would resume once Benioff and Weiss finished their ongoing commitments. In February 2019, Bloys said the series was still in development and not affected by the controversy, but stated in May 2019 that it was "not on the front burner". In August 2019, it was announced that Benioff and Weiss had closed a multi-million dollar deal with Netflix and it was reported that the deal "wipes ''Confederate'' off HBO's books." In January 2020, Bloys confirmed that the project had been officially canceled without an episode even being made.

Although production was halted 7 weeks into the intended 8 weeks of filming, the format of the show, an ongoing competition with a definitive conclusion, meant that the final competition for the grand prize had not been filmed, and production's attempts to edit the show in absence of its proper conclusion were ultimately passed on. NBC president Susan Rosner Rovner had reportedly spent $18 million on the production of the show. Its slot for lead in program following the closing ceremony of the 2020 Summer Olympics was replaced by ''Family Game Fight!''. In early 2024, a contestant on the show revealed further details about the format in an AMA on Reddit: Contestants competed as duos, and one of the games was a giant version of skee-ball, in which contestants were launched down a slide over a giant pool to land in rings to score points.
