Casper Meets Wendy is a 1998 American fantasy comedy film based on the Harvey Comics cartoon characters Casper the Friendly Ghost and Wendy the Good Little Witch. The film is a sequel to Casper: A Spirited Beginning, and the second spin-off/prequel of Casper (1995). Saban Entertainment co-produced the project.

This was Hilary Duff's first major film, and was released on September 22, 1998, six days before her 11th birthday. The film also marks the second Casper film for co-star Cathy Moriarty, who previously starred as the main antagonist in the 1995 film.

The film was met with mostly negative reviews from critics, but was considered an improvement to its predecessor. Its television premiere was October 24, 1999 on Fox Family.
