"Quicksilver Lightning" is a song by Roger Daltrey, who at the time was the former lead singer of The Who. The track is credited as being written by Dean Pitchford and being composed by Giorgio Moroder. The track is the theme tune for the 1986 film Quicksilver starring Kevin Bacon, Jami Gertz, Paul Rodriguez, Louie Anderson, Laurence Fishburne and Rudy Ramos. The film was directed by Thomas Michael Donnelly. The film went quite unnoticed, so both the song and the film are not easily remembered.

The song was released as a single on April 1986, and was a minor success on the Billboard Mainstream Rock Charts, reaching number 11.

A large portion of the music video was filmed in San Francisco, California, with parts of the video featuring Daltrey recording the song in a studio. The video begins with Daltrey in a taxicab, looking at documents called "Quicksilver", while Jack Casey (Kevin Bacon) rides behind him. He gets out of the cab and walks into a recording studio, then begins singing the song. The video cuts between Daltrey singing and scenes from the film.

The song was later released as the B-side to the single, Hearts of Fire from Daltrey's seventh solo studio album Can't Wait to See the Movie, in 1987.

The B-side Love Me Like You Do, written by Andy Nye, was included as track six on Daltrey's sixth solo album, Under a Raging Moon, but only on the CD and tape versions, not the record version.
