Charmed is an American fantasy drama television series developed by Jennie Snyder Urman, Jessica O'Toole, and Amy Rardin. It is a reboot of the WB series of the same name, created by Constance M. Burge, which originally aired from 1998 to 2006. Charmed premiered in the United States on October 14, 2018, on the CW. Carter Covington served as showrunner for the first season, before married duo Liz Kruger and Craig Shapiro took over for the second and third seasons. Jeffrey Lieber, Joey Falco, and Nicki Renna replaced Kruger and Shapiro as showrunners for the fourth season.

The first three seasons follow the lives of sisters Macy (Madeleine Mantock), Mel (Melonie Diaz) and Maggie (Sarah Jeffery), who, after the death of their mother, discover they are the Charmed Ones, the most powerful trio of good witches destined to protect both innocent lives and the world from demons and other dark forces. Each sister has an individual magical power, which is noticeably stronger when all three sisters work together as the "Power of Three" to defeat their enemies. The sisters are aided by a Whitelighter, Harry Greenwood (Rupert Evans), an advisor who protects and guides witches.

The reboot is known for being more diverse than the original series by casting three women of color in the lead roles, and for its LGBT representation by making one of the sisters a lesbian. Urman explained that television viewers already "had a chance to see three white witches" on the original Charmed, and that she was adamant on developing a different version of the series in which people of color and the LGBT community could see themselves represented onscreen and "be the hero of the story". The reboot sparked controversy from some cast members and fans of the original Charmed; Holly Marie Combs and Alyssa Milano both criticized the CW's decision to reboot the series without any involvement from the original cast or crew, while fans campaigned via Twitter to stop the network from moving forward with the pilot episode.

The first season of Charmed, which aired on Sundays, helped the CW return to original programming on Sunday nights for the first time since the 2008–09 U.S. television season. Charmed was renewed for a fourth season in February 2021, which premiered on March 11, 2022. In May 2022, it was announced that the fourth season would be its final season.

The series begins in the fictional college town of Hilltowne, Michigan, where sisters Mel (Melonie Diaz) and Maggie Vera (Sarah Jeffery) are living with their mother Marisol (Valerie Cruz), who shortly afterward is attacked and killed by an unknown dark force.

Three months later, Mel and Maggie discover that they have an older half-sister, Macy Vaughn (Madeleine Mantock), who was kept a secret by their mother for years but recently moved to Hilltowne for a new job at the local university the sisters attend. When Macy meets her sisters for the first time at the family's Vera Manor, lightning flashes and the house's power goes out, indicating the sisters' magical powers have been activated now that all three of them are together. Macy receives the power of telekinesis, middle sister Mel can freeze time, and Maggie, the youngest, can hear people's thoughts and feel their emotions.

Soon afterward, their Whitelighter—an advisor who protects and guides witches—Harry Greenwood (Rupert Evans) gathers all three sisters together in their attic; he reveals to the sisters that they are witches and presents them with their family's Book of Shadows – a spell book and guide to using the "Power of Three". Marisol had bound her daughters' powers when they were each born to protect them and let them live normal lives but was in the process of unbinding their powers on the night she was murdered. By the end of the first episode, Macy moves into the Vera Manor and the sisters ultimately accept their new destiny as the Charmed Ones, the most powerful trio of good witches who protect both innocent lives and the world from demons and other dark forces.

The reboot changes several elements from the original Charmed series, including moving the fictional setting from San Francisco to Hilltowne; making the middle sister a lesbian; giving the youngest sister the power of empathy instead of premonition; changing the family name from Halliwell to Vera; and having all three of the sisters' alliterative names begin with 'M' instead of 'P'. Additionally, the reboot has a more ethnically diverse cast: Mantock is Afro-Caribbean, Diaz is Puerto Rican, and Jeffery is African American, English and Indigenous Canadian. In the show, the sisters are of mixed ethnic background, having Latina, African-American and white heritage.
