"You Know My Name" is the theme song of the 2006 James Bond film Casino Royale, performed by American musician Chris Cornell, who wrote and produced it jointly with David Arnold, the soundtrack's composer.

[5] Cornell thought it was a strange offer, considering that he was American, and assumed he would perform a secondary song instead of the main theme.

He then went to Prague to visit the film's shooting location, and was impressed with its emotional content when he was shown a rough cut.

[5] Some of Arnold's ideas included the song's title, the heavy introduction, and "having the same genetic material as the Bond theme, but in a different order and in a different shape".

[8] After a demo of the song was approved by the film's producers,[9] both musicians recorded the full version in AIR Studios in London.

[16] And he jokingly stated "Casino Royale didn't make a good rock title, but I would write a song named Octopussy just for fun".

[20] The lyrics try to illustrate Bond's psyche in Casino Royale, described by Cornell as a conflicted and tough spy with more emotional depth, not the "superconfident, seemingly invincible, winking kinda ladies' man superspy" of the previous incarnations.

"[14] The song was also an introduction to the character, even though he has been in many previous movies—hence the title "You Know My Name"—dealing with Bond's actions such as his first assassination, "introducing himself to what may be the rest of his life and how he will live it and what it will mean.

A "Pop Mix" was used in the music video, featured on the Carry On album, and appeared on German singles as the second track.

It was released as a stand-alone single on December 14, 2006,[23] with a new acoustic version of the Soundgarden song "Black Hole Sun" on the B-side.

[26] The song's music video was directed by Michael Haussman, who tried to compare "the lives of a professional spy and a rock star".

[28] Finnish rock band Poets of the Fall covered the song in 2008 for the compilation CD Livenä Vieraissa.

[29] The Amalgamates, an a cappella group from Tufts University, performed an all vocal version of the song on their album Prime.

[34] Among music critics, Billboard described it as "the best Bond theme since 'A View to a Kill'", praising the minimal production.

[35] On its review of Carry On, the magazine considered "You Know My Name" to be the best track of the album, describing it as "some of Cornell's most uncomplicated and accessible music to date".
