"Casualty of Love" is a song by English recording artist Jessie J, from her debut studio album Who You Are (2011).

Written by Jessica Cornish, Farrah "Fendi" Fleurimond, Martin Kleveland, Natalie Walker and produced by Martin K, "Casualty of Love" was released digitally on 22 February 2011, as the only promotional single from the album, as part of the iTunes Store's.

Jessie J performed the song live in many locations, along with her other non-single hits such as "Abracadabra" and "Big White Room".

Idolator, "We have nothing bad to say about this lovely little track, which sounds like something Jennifer Hudson might belt over the closing credits of a Nicholas Sparks movie.

In other words, while we admire the craftsmanship of both the songwriting and singing, we’re afraid this may be too tepid to make much of a splash as a single".
