Best of Both Worlds Tour was the debut concert tour by American recording artist Miley Cyrus. The tour was held to promote the double-disc album Hannah Montana 2: Meet Miley Cyrus (2007), which consisted of the soundtrack to Hannah Montana's second season and her debut studio album. It initiated in October 2007 and concluded in March 2008, visiting cities in the United States and Canada. The tour was promoted by AEG Live and Buena Vista Concerts. Labelmates the Jonas Brothers, Aly & A.J., and Everlife each served as opening act during the tour. One dollar from each ticket sold was donated to the City of Hope National Medical Center, an organization devoted to the fight against cancer. The Best of Both Worlds Tour raised over US $2 million for the organization.

The Best of Both Worlds Tour was created, by Kenny Ortega and Michael Cotten, to be video intensive and was meant to differentiate Cyrus from Hannah Montana as a performer. The show had Cyrus performing first under character, as Hannah Montana. She then performed a duet with the opening act, which continued performing an interlude of songs. For the latter half of the duet, a body double was used to facilitate the transition from Hannah Montana to herself. Videos online caused many fans to become outraged and question whether Cyrus lip-synched on the tour. Her representatives later issued a statement that denied the allegations and stated the reasons for the body double's usage. The fast-paced concert had six segments, divided equally between each persona.
