Marcel Dadi (1951-July 17, 1996) was a French guitarist known for his country & western music. He was a personal friend of country star Chet Atkins. He has used his talents to create some instructional videos.

Dadi was one of the 230 people killed when TWA Flight 800 exploded off the coast of Long Island. He was returning to France after being honored at Nashville's Country Music Hall of Fame.

Atkins had this to say about his friend: "I have lost one of my best friends. Sometimes I think he loved me as if I were one of his family. I feel the same way about him."
