Henry Fool (1997) is a seriocomic film directed, written, and produced by Hal Hartley, featuring Thomas Jay Ryan, James Urbaniak, and Parker Posey. As in The Unbelievable Truth, an earlier Hartley film, expectation and reality again conflict.

The film won the best screenplay award at Cannes Film Festival, where it was also nominated for the Golden Palm.
A sequel, titled Fay Grim, was released in 2007.
