"Next in Line" is the third single by Australian progressive/alternative rock band Dead Letter Circus. It was preceded by the singles "Reaction" (also featured as a B-side to "Next in Line") and "Disconnect and Apply". It was released on the first of November, 2008, and was distributed, like the Dead Letter Circus EP, through MGM Distribution. Like the band's EP, the whole of "Next in Line" was available for purchase through the iTunes Store. Both "Next in Line" and "Reaction" are featured on the band's debut studio album This Is the Warning.
The version of the single from the iTunes Store, had an exclusive bonus track called "Inferiority Complex".

The remix was done by Australian funk rock band Mammal and features vocals by Mammal's vocalist Ezekiel Ox.
