"We are heartbroken to announce the passing of our beloved Gilbert Gottfried after a long illness," his family wrote Tuesday in a statement shared on his verified Twitter account.
Gottfried, who had been living in South Florida for the past few years, made a name for himself with his piercing voice and often crude humor.
The Brooklyn-born stand-up comedian had been a fixture of the New York comedy club scene in the 1970s, but his chance to catapult into the mainstream came in 1980, when he joined the cast of NBC's "Saturday Night Live" for its sixth season.
