"Niagara Falls (Foot or 2)" is a song by American record producer Metro Boomin, American rapper Travis Scott, and British-American rapper 21 Savage, from Metro's second studio album Heroes & Villains (2022). It was written by the artists alongside Allen Ritter, My Best Friend Jacob, and Peter Lee Johnson, the latter three producing it with Metro.
Cactus Jack Records' Chase B and Travis Scott first previewed the song on their podcast .WAV Radio in October 2020. The song leaked in January 2021 on Spotify, but was soon removed from the platform. On November 30, 2022, Metro Boomin revealed on Twitter that the song would be on his album Heroes & Villains, which was then released a few days later.
The song features a trap beat with a "chilling" piano loop.
The song received generally positive reviews from critics. Robin Murray of Clash wrote, "'Niagara Falls (Foot Or 2)' is a real highlight â it's never less than entertaining." Mosi Reeves commented on 21 Savage's line "Mike Vick, number 7, I'm a dog", calling it a "funny" reference to the Bad Newz Kennels dog fighting investigation. Hamza Riaz regarded the song as one of the best tracks from Heroes & Villains.
