Danny Gatton (September 4, 1945 – 4 October 1994) was a talented and enigmatic American guitarist who committed suicide at his Maryland home in 1994 while still relatively unknown to the public.

Gatton was born in Washington, DC on September 4, 1945. His father, Daniel W. Gatton Sr., was a former rhythm guitarist known for his unique percussive style, who left his musical career to raise his family in a more stable profession. The younger Gatton grew up to share his father's passion for the instrument.

Gatton's playing combined musical styles such as jazz, blues and rockabilly in an innovative fashion, and he was known by some as "the telemaster" or "the world's greatest unknown guitarist". However, he never achieved the commercial success that his talent arguably deserved. His skills were most appreciated by his peers such as Eric Clapton, Willie Nelson, and his childhood idol Les Paul.

Danny Gatton made his name as a performer in the Washington, D.C. area during the 1980s, both as a solo performer and with his Redneck Jazz Explosion, in which he would trade licks with virtuoso pedal steel player Buddy Emmons over a tight bass-drums rhythm which drew from blues, country, bebop and rockabilly influences. He also backed Robert Gordon and Roger Miller.

He usually played a 1953 Fender Telecaster (Fender now manufactures a replica of his heavily customized instrument), with Joe Barden pickups and Fender Super 250L's, or Nickel Plated Steel (.010 to .046 with a .015 for the G) strings. As a slide Gatton would use a beer bottle or mug.

His technique was unorthodox, but allowed him to use all ten fingers for both picking and fretting. He always played with a jazz style teardrop pick, and was capable of intricate passages combining bluegrass, bebop, and garage sounds, executed with amazing clarity and at dizzying speeds.
