"Work" is a song recorded by Australian rapper Iggy Azalea for her debut studio album, The New Classic (2014). It was released as Azalea's debut single as a lead artist, and the album's lead single on 17 March 2013. The track was written by Azalea, Trocon Markous Roberts, Natalie Sims, and The Invisible Men who produced it with 1st Down of FKi. Hailed by Azalea as her most personal song, "Work" was developed with motivational and inspirational intentions to portray her life story; specifically dealing with her struggle as an up-and-coming rapper, and her relocation from Mullumbimby, New South Wales to Miami at age 16. In sequence with its lyrical story, the snap and trap track begins with a sad-stringed verse segment before significantly increasing in tempo at its drum and synth-heavy refrain.

A number of music critics consider the song to be among Azalea's best output, namely praising her flow and the depth of the lyrical content. Commercially, "Work" became a sleeper hit; it peaked at number 17 on the UK Singles Chart and number 54 on the US Billboard Hot 100, but was certified silver and platinum by the British Phonographic Industry (BPI) and Recording Industry Association of America (RIAA), respectively. "Work" became one of the lowest peaking songs to receive a sales certification in Australia where it reached number 79 and was certified gold by the Australian Recording Industry Association (ARIA).
