"The Power of Love" is the title of a 1985 single by Huey Lewis and the News written for and featured in the 1985 blockbuster film Back to the Future. It gave the band their first number-one hit on the U.S. Billboard Hot 100, their second number-one hit on the U.S. Top Rock Tracks chart, and was a top ten hit on the UK Singles Chart, where it appeared on UK editions of the band's fourth studio album, Fore!. The song was nominated for an Academy Award at the 58th Academy Awards.

The song appears early in Back to the Futureas Marty McFly (Michael J. Fox) skateboards to school, then when he and his band played the song for a Battle of the Bands auditions (which Lewis, himself, is judging, and tells Marty's group that they "are just too darn loud"), and later when Marty returns to his neighborhood. In the sequel, Back to the Future Part II, the 2015 version of Marty attempts to play the song on his guitar just after being fired, but ends up playing it very poorly due to his damaged hand from his 1985 accident with a Rolls-Royce. Finally, it can be briefly heard playing in the car where Needles and his buddies are driving when Needles challenges Marty to the fate-determining car race near the end of Back to the Future Part III.

The music video shows the band playing in a nightclub with Dr. Emmett Brown (Christopher Lloyd) showing up in his DeLorean, apparently after time-traveling, and a couple stealing it for a joy ride.
