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

Among his 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 genre, both for the technical difficulty of the exploration and the quality of its production. Meauxsoone has also explored other themes related to rock art and Christian troglodyte art, focusing on both the archaeological aspect and the human dimension of these subterranean worlds.

Guy settled in the Vercors region in 1983, traveling the world with his camera, producing over 100 television reports. A lover of the Vercors, Guy left the small screen behind and founded the web TV association VercorsTV in 2010: a team that produces and broadcasts online reports from all angles about the mountain range. Highlighting its natural, heritage, and historical richness, Guy uses numerous archives, including those from the Resistance, the Father Gavet collection, and the Olympic Games. The VercorsTV project has fascinated him throughout the years, with 700 documentaries online at vercors-tv.com.

His 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. Guy Meauxsoone is a guest of honor at major caving events, recognized for his "impressive track record" and his contribution to the audiovisual heritage of the discipline.

Guy Meauxsoone passed away on June 14, 2023, at the age of 76 in Autrans-Méaudre, Vercors. The Vercors Natural Park paid tribute to him in its August 2023 newsletter.
