Rugrats Go Wild (originally titled The Rugrats Meet the Wild Thornberrys) is a 2003 American animated crossover adventure film based on the Nickelodeon animated television series Rugrats and The Wild Thornberrys. It is the final installment of both the Rugrats and The Wild Thornberrys film series and the sequel to both the films Rugrats in Paris: The Movie (2000) and The Wild Thornberrys Movie (2002). The film was the first to feature Nancy Cartwright as the voice of Chuckie Finster following original voice actress Christine Cavanaugh's retirement in 2001. The film follows the Rugrats and their families as they prepare for their planned vacation, but eventually get stranded on an uncharted island in the Pacific, where they meet the Wild Thornberrys for the first time.

The film was produced by Nickelodeon Movies and Klasky Csupo and released in theaters on June 13, 2003, by Paramount Pictures. Rugrats Go Wild grossed $55.4 million worldwide and unlike its predecessors, it received unfavorable reviews from critics. The film used "Odorama", which allowed people to smell odors and aromas from the film using scratch and sniff cards (reminiscent of 1960s Smell-O-Vision). This is the only Rugrats film to receive a PG rating by the MPAA.
