The Rugrats Movie is a 1998 American animated comedy film based on the Nickelodeon animated television series Rugrats. It was directed by Igor Kovalyov and Norton Virgien and was written by David N. Weiss & J. David Stem. The film features the voices of E. G. Daily, Tara Strong, Christine Cavanaugh, Kath Soucie, Cheryl Chase, Cree Summer, Jack Riley, Melanie Chartoff, Michael Bell and Joe Alaskey, along with guest stars David Spade, Whoopi Goldberg, Margaret Cho, Busta Rhymes, and Tim Curry. The film takes place between the events of the series' fifth and sixth seasons, and it follows Tommy Pickles as he and the rest of the Rugrats along with his new baby brother, Dil, eventually get lost into the deep wilderness after taking a high-speed ride on the Reptar Wagon, and embark on an adventure to find their way home in the forest while being pursued by circus monkeys and a predatory wolf along the way. The Rugrats Movie is the first feature film based on a Nicktoon and the first installment in the Rugrats film series.

Plans for a Rugrats film adaptation, along with Ren and Stimpy and Doug, began when Nickelodeon made a contract with 20th Century Fox to produce them. However, the contract ended after Nickelodeon's parent company, Viacom purchased Paramount Pictures' parent company Paramount Communications in 1994. Production then began in 1995 after the television series had restarted after a small hiatus.

The Rugrats Movie was released in the United States on November 20, 1998. The film received generally positive reviews from critics, though some criticized its darker tone compared to the television series. The film was a box office success, opening at #1 and grossing a total of $141 million worldwide. It became the first non-Disney animated film to gross over $100 million in the United States.

The film was followed by two sequels: Rugrats in Paris: The Movie in 2000 and Rugrats Go Wild in 2003, which is a crossover with The Wild Thornberrys.
