Thomas "Tommy" Bilotti (March 23, 1940 – December 16, 1985) was an American mobster who briefly served as underboss of the Gambino crime family in New York City.

The son of Italian immigrants Lillian (née Rosso) and Anthony Bilotti, he was born on the Staten Island borough of New York City.

[1] As a young man, Bilotti became an associate in the crew of John "Johnny D" D'Alessio, a caporegime in the Gambino crime family who controlled illegal gambling and other rackets on Staten Island.

Bilotti also spent time as the chauffeur and bodyguard of Alexander "The Ox" DeBrizzi, an uncle of the D'Alessio brothers who controlled the Staten Island waterfront for the Gambino crime family.

[6] Bilotti was a resident of 33 Kensington Avenue on Staten Island in April 1970, when he and an accomplice, Thomas Papanier, were observed discarding firearms and arrested following a shooting in Jamesburg, New Jersey.

Bilotti and Papanier were apprehended as they ran from the scene of the shooting, in which African-American teenager Emory Parks suffered superficial injuries when he was struck in the back of the head by birdshot pellets.

[7] The quick arrest of the pair occurred as the Jamesburg area was in the midst of significant racial tension after riots at the local high school, and police from Spotswood and Monroe Township were on alert.

[1] Although Castellano had worked hard to cultivate a sophisticated image, he chose the thuggish Bilotti as his protégé because he was "vigilant, hardworking, fearless, and, above all, loyal", according to O'Brien and Kurins.

[6] The agents described his traits: "As long as he was waiting on Paul Castellano, Tommy Bilotti was deferential, subdued, watchful yet calm, like a dog on a rug.

[6] In one incident, Bilotti entered a Staten Island bar armed with a baseball bat to collect an interest payment from the owner, who was still recovering and trying to pay medical bills from a beating sustained weeks earlier.

[6] O'Brien was warned by Bruce Mouw, the supervisor of the FBI's Squad C-16, which was assigned to investigate the Gambino crime family: "Don't ever talk to Tommy Bilotti alone.

Soon he was just spitting out curses wrapped in random phrases, his face purple, his nostrils distended, ropy veins standing out on his pit-bull neck".

The pair were partners in Scara-Mix, a concrete-supply company headquartered at 2537 Richmond Terrace in West New Brighton which continuously won profitable contracts.

[16][17] He was also heavily involved in the Steam Fitters Local 638 of the Plumbers Union that was represented by George Daly, an associate who belonged to Bilotti's crew.

[24] The main conspirators who composed the dissident faction were Gotti, Joseph "Joe Piney" Armone, Frank "Frankie D" DeCicco, Robert "DB" DiBernardo and Salvatore "Sammy the Bull" Gravano – collectively known as "the fist".

[26] Secondly, Castellano named his bodyguard Bilotti as the new underboss, a decision which caused insult to other members of the family who felt they were more deserving of the position.

[29] On Monday, December 16, 1985, Bilotti drove Castellano to the prearranged early evening meeting at Sparks Steak House in Midtown Manhattan, on East 46th Street near Third Avenue.

[30] A hit team (Salvatore Scala, Edward Lino, and John Carneglia) waited near the restaurant entrance; positioned down the street were backup shooters Dominick Pizzonia, Angelo Ruggiero, and Tony Rampino.

[43][44] On April 2, 1992, with the help of Gravano becoming a government witness, Gotti was convicted of numerous racketeering charges, including the 1985 Castellano and Bilotti murders.
