The Unseen is a 1980 American slasher film directed and written by Danny Steinmann (credited as "Peter Foleg’), and starring Stephen Furst, Barbara Bach, Sydney Lassick, and Lelia Goldoni. Its plot follows three female news reporters who arrive in Solvang, California, to cover the town's annual Danish festival, and end up staying in the Victorian home of a middle-aged couple harboring a dark secret in their basement.

The film originally began with a screenplay by Michael Viner and Kim Henkel, which was significantly altered and rewritten by Steinmann and Michael L. Grace.
