Messy is the debut studio album by English singer Olivia Dean.

[6] Sophie Williams of NME rated the album 4 out of 5 stars, complementing Dean's "confidence to occasionally dissect subjects that others swerve" while keeping a "mainstream" appeal.

[11] Writing for The Line of Best Fit, Izzy Sigston deemed the singer as "the master of versatility",[12] and commended the wide range of the album.

Alim Kheraj of The Guardian was a little critical of the album, hoping that "Dean will relinquish the tired neo-soul fodder to pursue the experimentation she’s clearly capable of".

[9] However, Robin Murray of Clash called the album "a bold, impressive debut offering" while commending the album's "broad range" and "precise execution".
