Joseph Francis Mazzello III (born September 21, 1983) is an American actor, director and screenwriter, known for his roles as Tim Murphy in Jurassic Park, Eugene Sledge in the HBO miniseries The Pacific, and Dustin Moskovitz in The Social Network.

Born in Rhinebeck, New York, and raised in Hyde Park, New York, the son of Virginia (née Strong) and Joseph Mazzello, Jr., who owned a performing arts school. He has one older sister, Mary Mazzello, and a younger brother, John Mazzello, who have both appeared in films. He is of three eighths Italian, as well as Polish, Irish, and German, descent. Mazzello went to Catholic school Our Lady of Lourdes. He is an alumnus of the University of Southern California, entering the USC School of Cinematic Arts in 2001 following a recommendation letter of director 'Steven Spielberg'. Mazzello paid for the course with his salary for a small appearance in The Lost World: Jurassic Park (1997), something the actor jokingly referred as "my graduation present from Spielberg".

Mazzello's first film appearance was a small role Presumed Innocent (1990), starring 'Harrison Ford'. He followed up that success with a supporting role as an abused child in the drama Radio Flyer (1992). His most notable roles were as Douglas Gresham in Shadowlands and Tim Murphy in Jurassic Park, both in 1993, Dexter in the 1995 film The Cure, and "Sledgehammer" Eugene Sledge in the HBO miniseries The Pacific. In 2010, Mazzello played Dustin Moskovitz, one of the co-founders of Facebook in the David Fincher-directed film The Social Network.
