Night Moves is a 1975 American neo-noir film directed by Arthur Penn, and starring Gene Hackman, Jennifer Warren, Susan Clark, with supporting performances from Melanie Griffith and James Woods. Its plot follows a Los Angeles private investigator who uncovers a series of sinister events while searching for the missing teenage daughter of a former movie actress.

Hackman was nominated for a BAFTA Award for his portrayal of private investigator Harry Moseby. The film has been called "a seminal modern noir work from the 1970s", which refers to its relationship with the film noir tradition of detective films. The original screenplay is by Scottish writer Alan Sharp.

Although Night Moves was not considered particularly successful at the time of its release, it has attracted viewers and significant critical attention following its videotape and DVD releases. In 2010, Manohla Dargis described it as "the great, despairing Night Moves (1975), with Gene Hackman as a private detective who ends up circling the abyss, a no‑exit comment on the post-1968, post-Watergate times."
