The Lost Children is a B-sides compilation album by American heavy metal band Disturbed.

The title comes from the band calling the songs "their children", because they can't pick a favorite.

[2] The Lost Children features all of Disturbed's B-side tracks that were recorded during a time period of 11 years with the exception of the song "Glass Shatters" which is only available on WWF Forceable Entry.

Florino states about the album, "One of the reasons why Disturbed stood out from the turn of the century pack is because they've always been as diverse as they are dangerous in their approach.

The band wasn't afraid to take risks, while crafting pulse-pounding, arena-filling heavy metal.
