What is the name of the actor who plays Paulie Walnuts?

The actor who plays Paulie Walnuts is Tony Sirico. Sirico portrays Paulie Gualtieri, the anxious, superstitious, and often brutally comic mobster known by his nickname “Paulie Walnuts.”

Paulie is one of the longest-serving members of Tony Soprano's crew. He is intensely concerned with rank, respect, and what other people say about him, yet he is also fiercely alert to threats against the family. His stories include a trip to Italy, a bitter conflict with Christopher Moltisanti, and repeated attempts to strengthen his position within the DiMeo organization.

Tony Sirico had a distinctive background for the part: before becoming an actor, he had been arrested and served time for criminal offenses. He later built a screen career specializing in tough-guy roles, including appearances in films by Woody Allen and television projects such as Goodfellas and Miami Vice.

Paulie is sometimes confused with Silvio Dante, played by musician Steven Van Zandt, or Bobby Baccalieri, played by Steven Schirripa. Dominic Chianese played Corrado “Junior” Soprano. Sirico's performance made Paulie one of the series' most recognizable supporting characters.
