"The Perfect Drug" is a song by Nine Inch Nails written for the David Lynch film Lost Highway. It was released in 1997 on the Lost Highway soundtrack as well as a single from the score. Remixes of the song were released as an EP, "The Perfect Drug" Versions.

Though "The Perfect Drug" Versions acts as a single for the titular song, the original version does not appear on the EP. The track has also been included on international singles "We're in This Together, Part 3" and "Into the Void" without the ending truncated; the only audio release of it in North America being on the Lost Highway soundtrack. A music video for the song, directed by Mark Romanek, was included with the VHS compilation Closure and in The Work of Director Mark Romanek.

In September 2018 the band performed the song live for the first time at Red Rocks Amphitheatre.
