Bates Motel is an American psychological horror drama television series based on characters from the 1959 novel Psycho by Robert Bloch that aired from March 18, 2013, to April 24, 2017. It was developed by Carlton Cuse, Kerry Ehrin, and Anthony Cipriano for the cable network A&E.

A "contemporary prequel" to Alfred Hitchcock's 1960 film Psycho, it depicts the lives of Norman Bates (Freddie Highmore) and his mother Norma (Vera Farmiga) prior to the events portrayed in the film, albeit in a different fictional town (White Pine Bay, Oregon, as opposed to Fairvale, California) and in a modern-day setting. However, the final season loosely adapts the plot of the novel Psycho.

Max Thieriot and Olivia Cooke both starred as part of the main cast throughout the series's run. After recurring in the first season, Néstor Carbonell was added to the main cast from season two onward. Both Nicola Peltz and Kenny Johnson had main cast roles at different points throughout the series’s run.

The series begins in Arizona with the death of Norma's husband, after which Norma purchases the Seafairer motel located in a coastal Oregon town so that she and Norman can start a new life. Subsequent seasons follow Norman as his mental illness becomes dangerous, and Norma as she struggles to protect her son, and those around him, from himself. The series was filmed outside Vancouver in Aldergrove, British Columbia, along with other locations within the Fraser Valley of British Columbia.

A&E chose to skip a pilot of the series, opting to go straight-to-series by ordering a 10-episode first season. Bates Motel is the longest-running original scripted drama series in the channel's history. The series's lead actors, Vera Farmiga and Freddie Highmore, received particular praise for their performances in the series, with the former receiving a Primetime Emmy Award nomination and winning a Saturn Award for Best Actress on Television. Bates Motel also won three People's Choice Awards for Favorite Cable TV Drama, and for Favorite Cable TV Actress (Farmiga) and Actor (Highmore).
