Robert Joseph Pastorelli (June 21, 1954 – March 8, 2004) was an American actor. He had many roles on TV, in movies, and on the stage, but is probably best known for the seven years he played the portly painter Eldin Bernecky on the television series Murphy Brown. His last role was as an oddball hitman in Be Cool, reuniting him with Michael star John Travolta.

Pastorelli was born in New Brunswick, New Jersey, the son of Dotty, an artist, and Ledo Pastorelli, an insurance salesman. Pastorelli had Italian heritage. His sister, Gwen Pastorelli, is an opera singer and a real estate agent. He was a 1972 graduate of Edison High School in Edison, New Jersey. He was an aspiring boxer until a near-fatal car crash on his 19th birthday cost him his dreams of becoming a professional boxer.

Pastorelli was found dead in his home at Hollywood Hills in 2004; a syringe, a spoon and a plastic bag with white powder were discovered near his body. His drug overdose death occurred at the time the authorities were reopening the investigation into the March 1999 shooting death of his then-girlfriend, 25-year-old Charemon Jonovich, at their home. Pastorelli, who knew of the investigation, had been considered a person of interest. The case, initially ruled an accident or undetermined, was closed after his death. The Coroners Office, after Pastorelli's death, changed the death certificate of Charemon Jonovich to homicide. The coroner's office later reported that he died of "acute cocaine-morphine (heroin) toxicity". His interment was located at Saint Catherine's Cemetery in Sea Girt, New Jersey.
