"Rainbow Connection" is a song from the 1979 film The Muppet Movie, with music and lyrics written by Paul Williams and Kenneth Ascher. The song was performed by Jim Henson as Kermit the Frog during the film's opening number, where it opens with Kermit sitting alone on a log in the swamp, playing the song on his banjo. The song is an integral part of Kermit's character's arc, since it establishes his dream of "making millions of people happy," which motivates his journey to Hollywood throughout the film.
"Rainbow Connection" reached No. 25 on the Billboard Hot 100 in November 1979, with the song remaining in the Top 40 for seven weeks in total. Williams and Ascher received an Academy Award nomination for Best Original Song at the 52nd Academy Awards.
In 2020, "Rainbow Connection" was deemed "culturally, historically, or aesthetically significant" by the Library of Congress and selected for preservation in the National Recording Registry.
