My Cousin Vinny is a 1992 American comedy film directed by Jonathan Lynn from a screenplay by Dale Launer. It stars Joe Pesci, Ralph Macchio, Marisa Tomei, Mitchell Whitfield, Lane Smith, Bruce McGill, and Fred Gwynne in his final film appearance before his death. The film was distributed by 20th Century Fox, and released in the United States on March 13, 1992.

Macchio and Whitfield play William Gambini and Stanley Rothenstein, two young New Yorkers who are arrested in Alabama and put on trial for a murder they did not commit. Unable to afford a lawyer, they are defended by Gambini's cousin Vinny Gambini (Pesci), newly admitted to the bar, who arrives with his fiancée, Mona Lisa Vito (Tomei). The clash between the brash Italian-American New Yorkers and the more reserved Southern townspeople provides much of the film's humor. The principal location of filming was Monticello, Georgia.

My Cousin Vinny was a critical and financial success, with Pesci, Gwynne, Macchio and Tomei praised for their performances. Tomei won the Academy Award for Best Supporting Actress. Attorneys have also lauded the film for its accurate depiction of criminal procedure and trial strategy.
