Fay Grim is a 2006 espionage thriller film written and directed by Hal Hartley. The film is a sequel to Hartley's 1997 film Henry Fool, and revolves around the title character, played by Parker Posey, the sister of Simon Grim (James Urbaniak). The plot revolves around Fay's attempt to unravel an increasingly violent mystery in Europe.

Hartley began writing the script in 2002, and filming took place in Europe from January to March 2006. It premiered in September at the 2006 Toronto International Film Festival, and received a theatrical release in the United States on May 18, 2007. The film was shot almost entirely in Dutch angles, meaning the vast majority of shots are framed diagonally, or "tilted". At the 2007 Sundance Film Festival, Hartley revealed that the two shots in the film's final cut that are not "Dutched" occurred when he and the film crew forgot to tilt the camera.

A sequel, Ned Rifle, was released in 2014.
