"Everybody's Fool" is the fourth and final single from the album Fallen by Little Rock, Arkansas band Evanescence. The song is, according to Amy Lee, about fake celebrities who strip and sell their bodies for publicity, though it could also be interpreted that the song is about celebrities who have completely false images. It has been misinterpreted as a message against Christian faith. The unifying theme of the video is that they are merely peddling lies.

After the release of third Fallen single "My Immortal", there wasn't any news from Evanescence. Rumours started going around that "Imaginary" (track 7 on Fallen) would be their last single released from that album. After release dates changing over and over again, everyone was surprised when "Everybody's Fool" was released (in "Episode #101", the first episode of MTV2's Video Mods, which first aired in 2004, "Everybody's Fool" was portrayed as performed by Rayne, the main character of the BloodRayne video games).

"Imaginary" was one of the very early songs written by Evanescence and was a local favorite from their small following in Little Rock. The first released version is on the Evanescence EP released in 1998, and was intended to be released as the fourth single. However, due to a decision made by Evanescence's record label, Wind-Up Records, "Everybody's Fool" was made the fourth single instead.

"Everybody's Fool" had a demo version which featured a different bridge (with a mechanical-sounding voice, not unlike the one featured on "Understanding"), and small portions of slightly distorted voices on the vocal track.

The music video features Amy dressed up as various ad features of products made by a company called 'LIES'. During an interview on MuchOnDemand, Amy has mentioned that the video for this song was her least favourite video.
