Adrian Frederick Smith (born in London, England on February 27th, 1957) is an English musician, best known as the guitarist of Iron Maiden.
Smith grew up in London and became interested in music at 15. He soon formed a friendship with future Iron Maiden guitarist Dave Murray, who inspired him to take up the guitar. After leaving school at 16, he formed a band called Urchin, which he led until their demise in 1980.
He joined Iron Maiden in November 1980, replacing Dennis Stratton, but he left the band after 10 years, in 1990. In 1999, Smith returned to the band, along with vocalist Bruce Dickinson.
Smith contributed to all of Iron Maiden releases from Killers to Maiden England, then from Brave New World to present.
