The Care Bears Adventure in Wonderland is a 1987 animated musical fantasy film and the third theatrically released film in the Care Bears franchise. It was released in the United States and Canada on August 7, 1987, by Cineplex Odeon Films, and is based on Lewis Carroll's Alice stories. The fourth feature film made at Toronto's studio Nelvana Limited, it was directed by staff member Raymond Jafelice and produced by the firm's founders (Michael Hirsh, Patrick Loubert and Clive A. Smith). It stars the voices of Keith Knight, Bob Dermer, Jim Henshaw, Tracey Moore and Elizabeth Hanna. In the film, the Care Bears must rescue the Princess of Wonderland from the Evil Wizard and his assistants, Dim and Dumb. After the White Rabbit shows them her photo, the Bears and Cousins search around the Earth for her before enlisting an unlikely replacement, an ordinary girl named Alice, to save her true look-alike. Venturing into Wonderland, the group encounters a host of strange characters, among them a rapping Cheshire Cat and the Jabberwocky.

Adventure in Wonderland was co-produced and self-financed by Nelvana Limited, after a consortium of American companies helped them with the first two films. Animation was handled by Nelvana Limited and Taiwan's Wang Film Productions. The film featured a musical score by Patricia Cullen along with songs by pop musicians John Sebastian and Natalie Cole. Upon its North American release, the film opened weakly to mixed reviews, and ended up with a $2.6 million gross; worldwide, it barely made back its $5 million cost. In the years since it opened, the film has received a VHS and DVD release in various countries outside North America, where distributors refuse to release it due to various complications involving the negative response of its first sequel, leaving this movie abandoned in the US ever since.
