My World is the debut extended play (EP) by Canadian recording artist Justin Bieber. It was released on 17 November 2009, by Island Records. The album is considered the first half of a two-piece project, later being supplemented by his debut studio album My World 2.0 (2010). After signing a recording contract in light of his growing popularity on YouTube, Bieber worked with collaborators including his mentor Usher, in addition to producers Tricky Stewart, The-Dream, and Midi Mafia. Its music incorporates pop and R&B styles, and lyrically discusses teen romance and coming of age situations.

Upon its release, My World received generally favorable reviews from music critics, who complimented its production. It debuted at number six on the US Billboard 200 with first-week sales of 137,000 copies. In doing so, it became the strongest-debuting release for a new artist in 2009, though it was topped the following week by I Dreamed a Dream by Susan Boyle, which moved 701,000 units. Upon the release of My World 2.0 in March 2010, its predecessor peaked at number five. Less than two months after its release, the record was certified platinum by the Recording Industry Association of America (RIAA) for sales exceeding one million copies. Internationally, the extended play attained similar success. It debuted atop the Canadian Albums Chart, where it was later certified double platinum. It additionally attained double platinum recognition in the United Kingdom.
