Hannah Montana is an Emmy Award-nominated American television series, which debuted on March 24, 2006 on Disney Channel. The series focuses on a girl who lives a double life as an average teenage school girl named Miley Stewart (played by Miley Cyrus) by day and a famous pop singer named Hannah Montana by night, concealing her real identity from the public, other than her close friends and family.

Michael Poryes, who is credited as co-creator, also co-created the hit Disney Channel Original Series That's So Raven. The show is produced by It's a Laugh Productions, Inc., in association with Disney. It is filmed at Tribune Studios in Hollywood, California. The series premiere scored record ratings for Disney Channel: 5.4 million viewers, a response "beyond our wildest expectations," according to the president of Disney Channel Entertainment.

The original idea for this show was based on the That's So Raven episode "Goin' Hollywood", which was supposed to be the pilot episode for a sitcom called Better Days, in which a child star of a popular TV show of the same name was to try her hand at going to a normal school. The episode "New Kid in School" has the basic premise as that aforementioned episode. Other names considered for the title were The Secret Life of Zoe Stewart (discarded as too similar to Zoey 101 on Nickelodeon), The Popstar Life!, and Alexis Texas. Former American Juniors finalist Jordan McCoy and pop and R&B singer JoJo (who rejected the role) were considered for the role of Zoe Stewart. Miley Cyrus originally auditioned for the role of the "best friend" Lilly Romero, later changed to Lilly Truscott, but they thought she would be better for the main character, so she tried out for Zoe Stewart/Hannah Montana. Zoe Stewart was later changed to Chloe Stewart, which was eventually changed to Miley when she got the part. The names of Hannah Montana were changed a few times. Three of the previous names were Anna Cabana, Samantha York, and Alexis Texas.

In December 2006, Disney announced plans to release Hannah Montana products, including: clothing, jewellery, apparel, and dolls, at select stores. Play Along Toys released the Hannah Montana fashion dolls, singing dolls and Miley Stewart doll, and other merchandise in August 2007. More Hannah dolls were released in November, along with Oliver, Lilly, and later Jake Ryan dolls. They became one of the most popular Christmas toys in 2007. Hannah Montana is signed for at least one more season according to Disney Channel. Filming for the second season started in December. The 2ND season started in April, 2007, in which she is in high school. As stated by Jason Earles at the launch of the High School Musical 2 Extended Edition DVD, filming of the second season has finished.

The theme song for Hannah Montana is "The Best of Both Worlds" written by Matthew Gerrard and Robbie Nevil, produced by Gerrard and performed by Miley Cyrus (as Hannah Montana). John Carta, who also composes the music cues to signify scene changes and commercial breaks, composed the music for the song. The song's lyrics describe the basic premise of the television series.

The full-length version, which is 2 minutes, 54 seconds in length, was included on the show's soundtrack, released in October 2006. For the TV version of the theme, which lasts only 50 seconds, only the first two stanzas and the last two were used.

"Just Like You" and "The Other Side of Me" were originally tested for the opening theme song, before "Best of Both Worlds" was chosen as the theme. Stage and features episode clips of each cast member when each cast member's name appears. Each cast member's name is "wiped" on the screen in a marquee-light-style. The sequence then switches to full-screen episode clips (most of the clips used in the Season One version of the sequence were of the early produced episodes) with the creator's names appearing in the second-to-last clip. The show's title logo design appears at the beginning, and again at the end, of the sequence (the latter portion as with most other portions of the sequence on the "concert stage" feature Cyrus as her character Hannah Montana).

In Season 3, a new version of the opening credits were used. It features Miley as herself and Hannah Montana in a Times Square-like setting. The names of the actors and actresses and clips from the show appear in a sort-of marquee board and it features Hannah Montana with her new wig and clothes style. The song playing is the new version of The Best of Both Worlds.
