Dominick "Skinny Dom" Pizzonia (born November 19, 1941) is a New York mobster and captain with the Gambino crime family who was a hitman and loanshark. Pizzonia allegedly participated in several high profile murders.

Born in the Ozone Park section of Queens, Pizzonia began working for the Gambino family as a crew member for then caporegime John Gotti. He was called "Skinny Dom" to distinguish himself from Gambino mobster Dominick "Fat Dom" Borghese.

On December 16, 1985, Pizzonia allegedly participated in the assassinations of Gambino boss Paul Castellano and underboss Thomas Bilotti outside a Manhattan steakhouse. After Castellano's murder, Gotti took over as family boss.

In June 1988, Pizzonia allegedly murdered mobster Frank Boccia at the family's request. The Gambinos ordered Boccia's murder because he had punched his mother-in-law, the wife of imprisoned mobster Anthony Ruggiano. Pizzonia and Gambino associate Alfred Congiglio lured Boccia to a social club, killed him, took his body on a boat, and dumped the body into the ocean off New York City. Boccia's body was never recovered.
