John Anthony White (né Gillis; born July 9, 1975) is an American musician who served as the guitarist and lead singer of the rock duo the White Stripes. A key artist of the 2000s garage rock revival, he is known for his distinctive musical techniques and eccentricity. He has won 12 Grammy Awards among other accolades. Rolling Stone included him on their 2010 and 2023 lists of the greatest guitarists of all time. The New York Times called White "the coolest, weirdest and savviest rockstar of our time" in 2012.

After moonlighting in several underground Detroit bands as a drummer, White founded the White Stripes with fellow Detroit native and then-wife Meg White in 1997. Their 2001 breakthrough album, White Blood Cells, brought them international fame with the single and accompanying music video for "Fell in Love with a Girl". White subsequently began collaborating with artists such as Loretta Lynn and Bob Dylan. In 2005, White founded the Raconteurs with Brendan Benson, and in 2009 founded the Dead Weather with Alison Mosshart of the Kills. In 2008, he recorded "Another Way to Die", the title song for the 2008 James Bond film Quantum of Solace, alongside Alicia Keys, making them the only duet to perform a Bond theme. White has released five solo studio albums, which have garnered critical and commercial success.

White is a board member of the Library of Congress' National Recording Preservation Foundation. His record label and studio Third Man Records releases vinyl recordings of his own work as well as that of other artists and local school children. His second studio album, Lazaretto (2014), broke the record for most first-week vinyl sales since 1991, holding that record until 2021. White has an extensive collection of guitars and other instruments and has a preference for vintage items that often have connections to famous blues artists. He is a vocal advocate for analog technology and recording techniques.

White has been known to create misdirection about his personal life. He and Meg White married in 1996, but divorced in 2000 before the height of the White Stripes' fame. They then began calling themselves siblings. He was married to model and singer Karen Elson from 2005 to 2013; they have a son and daughter. In 2022, he married musician Olivia Jean. He currently resides in Nashville, Tennessee.
