"Ready, Set, Don't Go" is a country song performed by American recording artists Billy Ray Cyrus and Miley Cyrus. It was released as the lead single from Home at Last, Cyrus' tenth studio album. It was sent to country radio stations on July 11, 2007 with a radio edit as a B-side. The song is a soft country ballad with some use of pop and soft rock elements. The song has received different interpretations though, in actuality, Cyrus wrote the song several years before its release when his middle daughter, Miley, moved to Los Angeles in order to pursue an acting career with an audition for the Disney Channel Original Series Hannah Montana. "Ready, Set, Don't Go" received critical praise, with reviewers complimenting its lyrical content. It also reached positive commercial responses for Cyrus, compared to his downfall in previous years. Peaking at number 85 on the Billboard Hot 100, it became Cyrus' first entry on the chart since "You Won't Be Lonely Now" (2000).
The song's accompanying music video was directed by Elliot Lester and features some of Cyrus' home videos; it received a CMT Music Award nomination at the 2008 CMT Music Awards. The song eventually became re-released as a duet with his daughter, pop star Miley Cyrus, in October 2007. At the time of the single's release, she was 14 and enjoying the success of her debut album Meet Miley Cyrus. The duet version became Miley's debut in country music and received better commercial outcomes. It reached its highest international peak in the Billboard Hot 100 at number 37 and became Cyrus' first international chart entry since "Could've Been Me" (1992). Cyrus, with and without his daughter, performed the song at several venues, most notably Miley's first headlining concert tour, the Best of Both Worlds Tour.
