Réginald Charles Gagnon (7 January 1949 – 29 May 2024), known professionally as Cayouche, was a Canadian singer and songwriter of Acadian descent.

[3] At the age of 19, he joined the United States Marine Corps and served in the Vietnam War, though he never saw combat.

In 1979, Gagnon returned to Canada with only his backpack and a guitar, which became the first step in his country-folk music career.

[2] His first album, Un Vieux Hippy, released in 1994, sold more than 15,000 copies in a fairly small market, and songs such as "La chaîne de mon Tracteur", "Export A", and "L'alcool au volant" attained relative popularity.

[7] Among his biggest hits are "Export A", "La chaine de mon tracteur", "L’alcool au volant", "Fume Fume", "C’est ça mon Acadie", and "La reine du bingo".
