John Clayton Mayer (pronounced /ˈmeɪ.ər/ MAY-ər; born October 16, 1977) is an American musician. Raised in Fairfield, Connecticut, he attended Berklee College of Music in Boston before moving to Atlanta, Georgia in 1997, where he refined his skills and gained a following. His first two studio albums, Room for Squares and Heavier Things, did well commercially, achieving multi-platinum status. In 2003, he won a Best Male Pop Vocal Performance Grammy Award for "Your Body Is a Wonderland".

Mayer began his career performing mainly acoustic rock, but gradually began a transition towards the blues genre in 2005 by collaborating with renowned blues artists such as B. B. King, Buddy Guy, and Eric Clapton, and by forming the John Mayer Trio. The blues influence can be heard on his album Continuum, released in September 2006. At the 49th Annual Grammy Awards in 2007 Mayer won Best Pop Vocal Album for Continuum and Best Male Pop Vocal Performance for "Waiting on the World to Change". He released his fourth studio album, Battle Studies, in November 2009.

Mayer's career pursuits have extended to stand-up comedy, design, and writing; he has written pieces for magazines, most notably for Esquire. He is also involved in philanthropic activities through his "Back to You" fund. Several high-profile romantic relationships and his involvement with the media caused him to become a tabloid staple, beginning in 2006.
