J.A.C.K. is the third studio album by American pop punk band Forever the Sickest Kids. It is their first release through Fearless Records since their former label, Universal Motown, was shut down, which resulted in the regular Motown being a separate label that still operates as of 2019. It is also the first release not to feature keyboardist Kent Garrison and lead guitarist Marc Stewart. The album was produced by Mike Green and was released on June 25, 2013.
