Paul Brett (20 June 1947 – 31 January 2024) was an English classic rock guitarist. He played lead guitar with Strawbs (although he was never actually a member), The Overlanders, The Crazy World of Arthur Brown, Elmer Gantry's Velvet Opera, The Velvet Opera, Tintern Abbey, Fire, Roy Harper, Al Stewart, and Lonnie Donegan. He switched to twelve-string guitar in the 1970s.

His first twelve-string guitar suite, Earth Birth, was released on his own label, Phoenix Future, and was produced by artist Ralph Steadman of Fear and Loathing fame. Critical acclaim led to Brett being signed on a four-album deal with RCA Records. His K-tel Romantic Guitar album went gold in the United Kingdom, but Brett stopped recording soon afterwards. He started recording again in 2000, with long-time friend and fellow twelve-string guitarist, John Joyce.

Brett wrote for music magazines Melody Maker, Sound International and International Musician and continued working in the music industry in the later part of his career. He latterly wrote a regular column for Acoustic, a magazine specializing in acoustic guitars. He was also the Associate Editor and Features Writer for Music Maker and Live in London magazines.

He has appeared on BBC Television's Antiques Road Show and Flog It in the mid-2000s.

Brett has worked as a guitar designer for Vintage Guitars in the UK, including The Viator 6 and 12 string travel guitars, The Gemini, The Viaten tenor guitar, and the Paul Brett signature 6 and 12 string guitars. Released in 2017 was the Statesboro' 12 string, which was a tribute to the blues musician, Blind Willie McTell.
