Mobsters is an American documentary television series that profiles the lives of infamous individuals in history; the series puts the spotlight on some of history's most infamous gangsters and all that went on during their reigns. The series airs on The Biography Channel.

Some episodes of Mobsters are rehashes of the similar TV Series American Justice as well as Notorious (TV series), both series that were originally broadcast on Biography Channel's sister channel, A&E Network; some episodes also rehash segments from another A&E series American Gangster, which began airing on the Black Entertainment Television channel. The only differences are the intro of the episodes and the lead-in's after commercials. Besides this, the rehashed episodes are no different in any way.
