The Secret Adventures of Tom Thumb is a 1993 British independent stop-motion/pixilation adult animated science-fantasy dystopian adventure horror film directed, written, shot and edited by Dave Borthwick, produced by bolexbrothers studio and funded by Richard Hutchinson, BBC, La Sept and Manga Entertainment, which also distributed the film on video.

The story follows the tiny Tom Thumb as he is abducted from his loving parents and taken to an experimental laboratory, and his subsequent escape. He discovers a community of similarly sized people living in a swamp, who help him on his journey to return to his parents. The film is largely dialogue-free, limited mostly to grunts and other non-verbal vocalisations.
