"All Around the World" is a song by Canadian singer Justin Bieber, from his third studio album, Believe (2012). It was written by Bieber, Sir Nolan and Nasri of The Messengers in collaboration with Ludacris, who guest features. This was the second collaboration between Bieber and Ludacris, having previously collaborated on "Baby" (2010). It was first released on June 4, 2012, as a promotional single from the album. The song was released as the fourth international single, and the fifth and final US single on February 26, 2013. The Eurodance track features a similar instrumentation to songs by Britney Spears, Chris Brown and Usher. Lyrically, it features Bieber singing to his love interest that "all around the world, people want to be loved". "All Around the World" received mostly positive reviews from music critics, who welcomed the song's Eurodance style. The song had moderate success worldwide, reaching the top ten in several countries, such as Belgium, Canada and Norway. Bieber promoted the song through live performances and a music video.

In late 2011, Bieber confirmed to radio network Capital FM that he was recording material for his third studio album, which was originally going to be released in early 2012. He later spoke to MTV News and revealed that Believe would surprise people in different ways, since it is musically a departure from his previous works. "All Around the World" was written and produced by The Messengers and Nolan Lambroza, while Bieber and Ludacris wrote additional lyrics. On May 25, 2012, an unmastered version of the track leaked online. The cover art for the promotional single was unveiled on June 4, 2012, and features Bieber holding an acoustic guitar over his shoulder, standing on the surface of the world, while the moon is glowing behind him. The same day, the track was released on iTunes Store through The Island Def Jam Music Group. The song was later released as the fourth international single, and the fifth and final US single on February 26, 2013.
