"Footloose" is a song co-written and recorded by American singer-songwriter Kenny Loggins. It was released in January 1984 as the first of two singles by Loggins from the 1984 film of the same name (the other one being "I'm Free (Heaven Helps the Man)"). The song spent three weeks at number one, March 31—April 14, 1984, on the US Billboard Hot 100, becoming Loggins' only chart-topper, and was the first of two number-one hits from the film. Billboard ranked it at the No. 4 song for 1984.

The song was very well received, and is one of the most recognizable song recorded by Loggins. When the American Film Institute released its AFI's 100 Years...100 Songs, "Footloose" reached the 96th position. The song was covered by country music artist Blake Shelton for the 2011 remake of the 1984 film.

It was nominated for an Academy Award for Best Original Song at the 1985 ceremony, losing to Stevie Wonder's "I Just Called to Say I Love You" from The Woman in Red.

The single version is slightly shorter in length compared to the album version. It begins with a soloed guitar track instead of a drum intro, and features more prominent backing vocals in the mix, particularly towards the end of the song.

In 2018, it was selected for preservation in the National Recording Registry by the Library of Congress as being "culturally, historically, or artistically significant.
