"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. The film producers chose Cornell because they wanted a strong male singer. Cornell and Arnold tried to make the song a replacement theme for the character instead of the "James Bond Theme" reflecting the agent's inexperience in Casino Royale, as well as an introduction to Daniel Craig's grittier and more emotional portrayal of Bond.

The track was leaked onto the Internet on September 20, 2006, and later released as an official single on November 13, 2006 through Interscope Records. It charted in many countries, notably peaking at No. 7 on the UK singles chart. It sold 148,000 copies in 2006 in the UK, and has sold 323,000 digital copies and garnered 3.5 million streams in the U.S. as of 2017. Reviews of the song were positive; it won the Satellite Award and the World Soundtrack Award, and was nominated for a Grammy Award. It was not included in the Casino Royale soundtrack, but appeared on Cornell's second solo album, Carry On.
