Guy Meauxsoone, born September 16, 1946, in Warneton, Belgium, is a French director and documentary filmmaker, renowned for his films devoted to underground exploration, caving, mountain sports, and the peoples of remote regions. He has particularly distinguished himself in the field of exploration documentary cinema, creating works that highlight underground worlds, their history, and their beauty.

Among Guy Meauxsoone's major achievements is the film Trou de Fer (1992), which documents the first complete descent of the canyon of the same name, a landmark feat in the history of caving and canyoning. This film is often cited as one of the most spectacular of its kind, both for the technical difficulty of the exploration and the quality of its production. Meauxsoone has also explored other themes, focusing on the discovery, sport, and ecology aspects, as well as the human dimension of the worlds he explores. His prolific work is praised for its ability to combine scientific rigor, a sense of adventure, and aesthetic qualities, offering a unique perspective on worlds often inaccessible to the general public. This rigor is evident, for example, in The Pillars of Dreams (1987), with Patrick Berhault and Patrick Cordier exploring the cliffs of Meteora, the mystical aerial refuges of hermits in Greece. Guy Meauxsoone is a guest of honor at major caving and mountain sports events, recognized for his "impressive track record" and his contribution to the audiovisual memory of the discipline, winning numerous awards and selections.
