"I Might Be Wrong" is a song by the English rock band Radiohead from their 2001 album, Amnesiac. In the United States, it was released as a radio-only single in advance of the album. "Pyramid Song" was the official first single in all other regions, and the "Pyramid Song" video was also released worldwide. The song charted at #27 on the Billboard Modern Rock Tracks chart.
Although the album version is heavily produced by Nigel Godrich and Radiohead, with a more electronic texture, "I Might Be Wrong" is one of the more guitar-oriented songs on Amnesiac.
