Hannah Montana is an American teen sitcom created by Michael Poryes, Rich Correll, and Barry O'Brien that aired on Disney Channel for four seasons between March 2006 and January 2011. The series centers on Miley Stewart (played by Miley Cyrus), a teenage girl living a double life as famous pop singer Hannah Montana, an alter ego she adopted so she could maintain her anonymity and live a normal life as a typical teenager. Episodes deal with Miley's everyday struggles to cope with the social and personal issues of adolescence while maintaining the added complexities of her secret identity, which she sustains by wearing a blonde wig. Miley has strong relationships with her brother Jackson (Jason Earles) and father Robby Ray (Billy Ray Cyrus), as well as her best friends Lilly Truscott (Emily Osment) and Oliver Oken (Mitchel Musso), who become aware of her secret. Overarching themes include a focus on family and friendships as well as the importance of music and discovering one's identity.

The Walt Disney Company commissioned the series after the success of Disney Channel's previous music-based franchises, such as the made-for-television film High School Musical (2006). Hannah Montana was produced by It's a Laugh Productions in association with Poryes's production company, and premiered on Disney Channel on March 24, 2006. A concert film, Hannah Montana & Miley Cyrus: Best of Both Worlds Concert, in which Miley Cyrus performs as Hannah Montana and herself, was released in 2008. The following year, the feature film Hannah Montana: The Movie was released. The series concluded on January 16, 2011, as a result of Cyrus's growing popularity and music career, and her desire to move into more mature acting roles.

Hannah Montana is one of Disney Channel's most commercially successful franchises. It received consistently high viewership in the United States on cable television and influenced the development of merchandise, soundtrack albums, and concert tours; however, television critics disliked the writing and depiction of gender roles and stereotypes. Hannah Montana helped launch Cyrus's musical career and established her as a teen idol; after Cyrus began developing an increasingly provocative public image, commentators criticized Hannah Montana as having a negative influence on its audience. The series was nominated for four Primetime Emmy Awards for Outstanding Children's Program between 2007 and 2010; Cyrus won a Young Artist Award for Best Performance in a TV Series, Leading Young Actress in 2008.
