"Niagara Falls" is the fourth single released by the American rock band, Chicago, from their 1986 album, Chicago 18. Lead vocals were shared by Jason Scheff and Bill Champlin. When writing the song, the band misspelled "Niagara" as "Niagra"; this mistake can be seen in the music video's title and most likely on the album, as Warner Bros. Records and Chicago never corrected it.

Following the successful singles, "Will You Still Love Me?" (#3 US pop) and "If She Would Have Been Faithful..." (#17 US pop), "Niagara Falls" only reached #91 on the Billboard Hot 100 pop singles chart.

Like the majority of Chicago's music videos from the late 1980s, the video for "Niagara Falls" featured various people shown throughout, with the main storyline revolving around a couple trying to make things work. The band itself never appears.
