Corrado John "Junior" Soprano Jr., portrayed by Dominic Chianese, is a fictional character from the HBO TV series The Sopranos. Usually referred to as "Junior" or "Uncle Jun" (pronounced “June”), he is the Boss of the DiMeo crime family for most of the series. However, he held little to no influence due to him being positioned as a front boss. A younger Corrado sometimes appears in flashbacks and is played by Rocco Sisto. Corey Stoll portrays a young Junior Soprano in the 2021 prequel film, The Many Saints of Newark. Dominic Chianese's performance as Junior received critical acclaim, garnering two Emmy nominations for Outstanding Supporting Actor In A Drama Series.
Junior is depicted as being intelligent, old-fashioned, stubborn and insecure about his power. Although Junior is portrayed as bitter and deceitful in season one, he shows a more considerate and humorous side of himself in the later seasons. He reveals a more sensitive aspect of his personality during his illness and house arrest. According to series creator David Chase, the name Junior was taken from one of his cousins. Chianese landed the role of Junior over Tony Sirico who played Paulie Gualtieri, and Frank Vincent who played Phil Leotardo.
