Not In Chronological Order is the debut studio album by American singer-songwriter Julia Michaels, released on April 30, 2021, by Republic Records.

The album's subject matter centers on themes of love, self reflection and ideal womanhood.

[8] Clash's Randy Radic thought Not in Chronological Order is soft in certain parts and "thick with sinew" in others, and equally allows Michaels to showcase her songwriting talent and "charismatic, oh-so-expressive voice".

[10] Alexis Petridis of The Guardian considered the album enjoyable and a display of Michaels's talent, but lacking in star quality.

[12] Writing for NME, Hannah Mylrea was favorable of its depiction of romance and Michaels's signature one-liners, adding, it "confidently chronicles every dizzying high and crushing blow that love brings – affairs of the heart have, after all, long been Michaels’ specialist songwriting subject".
