John Dawson "Johnny" Winter III (born 23 February 1944) is an American blues guitarist, singer and producer.

Johnny Winter is known for his southern blues and rock and roll style, as well as his physical appearance.

In 2003 Winter was ranked 74th in Rolling Stone magazine list of the "100 Greatest Guitarists of All Time".

His recording career began at the age of 15, when their band Johnny and the Jammers released "School Day Blues" on a Houston record label. During this same period, he was able to see performances by classic blues artists such as Muddy Waters, B. B. King and Bobby Bland. In the early days Winter would sometimes sit in with Roy Head and The Traits when they performed in the Beaumont, TX area, and in 1967 Winter recorded with The Traits releasing a vinyl 45 under the group's name, Tramp/Parchman Farm, Universal 30496. In 1968, he released his first album on Austin's legendary Sonobeat Records, The Progressive Blues Experiment.

Winter has since recorded for several labels, including Alligator Records and Point Blank records. He has mostly returned to and stayed with the blues that are his first musical love.
