The Parent Trap is a 1998 American romantic comedy film directed and co-written by Nancy Meyers in her feature directorial debut, and produced and co-written by Charles Shyer. It is a remake of the 1961 film of the same name and an adaptation of Erich Kästner's 1949 German novel Lisa and Lottie (Das doppelte Lottchen).

Dennis Quaid and Natasha Richardson star as a divorced couple who separated shortly after their identical twin daughters' birth; Lindsay Lohan stars (in her film debut) as both twins, Hallie Parker and Annie James, who are fortuitously reunited at summer camp after being separated at birth. David Swift wrote the screenplay for the original 1961 film based on Lottie and Lisa. Swift is credited along with Meyers and Shyer as co-writers of the 1998 version.

The film premiered in Los Angeles on July 20, 1998, and was theatrically released in the United States on July 29, and was a box-office hit, grossing $92.1 million against a $15 million budget. It received positive reviews from critics, with Lohan's performance, in particular, earning high praise.
