"That Should Be Me" is a song by Canadian recording artist Justin Bieber, included as the tenth and final track on his first studio album, My World 2.0, released on March 19, 2010. The song was written by Bieber alongside Luke Boyd and Nasri Atweh and Adam Messinger of The Messengers, the production team who produced the track. "That Should Be Me" is an orchestral ballad in which Bieber sings about losing his love, and according to Monica Herrera of Billboard, plays the "scorned ex." Most music critics positively received the song, and it debuted at number ninety-two on the Billboard Hot 100 following the release of My World 2.0. It also serves as the eighth track of Justin's first remix album My Worlds Acoustic.

In December 2010, it was announced that Bieber would be working with American country band Rascal Flatts on new music, presumably for his second studio album. However it was revealed that "That Should Be Me" was remixed to include vocals from the country group for the release of Bieber's second remix album, Never Say Never: The Remixes, released to accompany the release of his 3D concert-documentary film Justin Bieber: Never Say Never. A music video was released to accompany the remixed version of the song, which premiered during Rascal Flatts' ABC special, Rascal Flatts: Nothing Like This Presented by JC Penney.

"That Should Be Me" was co-written by Bieber alongside Luke Boyd, as well as Nasri Atweh and Adam Messinger of The Messengers, with the latter also producing the track. The song was recorded by The Messengers at NH Studios in North Hollywood, California. Instrumentation and all vocal arrangements were done by Atweh and Messinger. Additional engineering was performed by Pat Thrall, while the track was mixed by Manny Marroquin at Larrabee Studios, also in North Hollywood. The mix was assisted by Christian Plata and Erik Madrid, whereas Atweh and Luke Boyd perform background vocals on the song.
