Who You Are is the debut studio album by English singer-songwriter Jessie J. It was released on 28 February 2011 by Lava Records, Island Records and Universal Republic Records. In such a high demand and interest from fans, the release was advanced by a month from 28 March, as previously planned. Recording sessions took place between 2005 and 2011, with several other record producers contributing on the album such as Dr. Luke, Toby Gad and K-Gee, among others.

Who You Are received generally mixed reviews from contemporary music critics. It debuted at number 2 on the UK Albums Chart, selling 105,000 copies in its first week. The album debuted at number 11 on the US Billboard 200, with first-week sales of 34,000 copies. Two singles preceded the album: Jessie J's UK debut single "Do It Like a Dude" and "Price Tag" featuring B.o.B, which served as the US lead single. The third single, "Nobody's Perfect", became J's third consecutive top 10 hit in the United Kingdom. The fourth single from the album, "Who's Laughing Now" was released on 21 August 2011, peaking at number 16 on the UK Singles Chart. The title track, "Who You Are" was released as the album's fifth UK single on 13 November 2011.
