Being an FBI informant on The Sopranos is a risky proposition, often ending in death. New York snitch, Jimmy Petrille and Soprano family capo, Carlo Gervasi are the only known FBI informants to survive until the series end. Raymond Curto deserves notice for being a long time informer before dying of natural causes without ever being suspected. Listed below are characters who are known to have been FBI informants and their respective fates. Note that Albie Cianflone was likely an informant, but he should not be included on the list because his cooperation (if any) is debatable, unconfirmed and unknown.
