"Crazy Chick" is a song by Welsh recording artist Charlotte Church, released as the lead single from her fifth studio album, Tissues and Issues (2005).

It was written by Sarah Buras, Wirlie "Wyl-e" Morris, and Fitzgerald Scott and produced by Tore Johannson.

Church explained that this originated from her belief that early songwriting is substandard, so she relented to her record company and allowed them to include more single-worthy tracks on the album.

[3] Justin Myers of the Official Charts Company wrote that "Crazy Chick" was a "breath of fresh air [...] reminiscent of a '60s girlgroup" and complimented Church's vocals, noting that they resembled those of Christina Aguilera's at several instances.

[4] British columnist James Masterton said that, compared to Church's earlier classical work, "Crazy Chick" was underwhelming, calling her voice "too good" for the track and noting that Joss Stone would have performed the song better.
