Arthur Morgan "Arto" Lindsay (born May 28, 1953) is an American guitarist, singer, record producer and experimental composer. He is a 1974 graduate of Eckerd College in St. Petersburg, Florida.

He has a distinctive soft voice and an often noisy, self-taught guitar style consisting almost entirely of extended techniques, described by Brian Olewnick "studiedly naïve ... sounding like the bastard child of Derek Bailey"; his guitar work is contrasted frequently with gentler, sensuous Brazilian music themes.
