Nicolas Favresse, born in Brussels in 1980, is a Belgian climber renowned for his versatile style, encompassing sport climbing, trad climbing, and big wall routes, particularly in high mountains and polar regions. A member of the Belgian Alpine Club's Rock Climbing Team, he has frequently climbed with his brother Olivier Favresse and Sean Villanueva, participating in notable expeditions to Patagonia, Pakistan, Baffin Island, and Greenland.

Among his most celebrated achievements are the first ascent of Le Clou at Freyr, one of the first ultra-high-level routes in Belgium, as well as climbs such as Estado Crítico, Free Rider on El Capitan, The Secret Passage, Ledgeway to Heaven, and the South African route in the Paine Towers. He has also distinguished himself in trad climbing with demanding repeats and first ascents, reaching very high grades, making him one of the most complete climbers of his generation. His record also includes successes on big walls such as Salathé, El Corazón, and Riders in the Storm, often freestyle and on very long routes.

Beyond performance, Favresse is associated with a committed, creative, and adventurous approach to climbing, where style, autonomy, and exploration are as important as pure difficulty. This philosophy has earned him significant international recognition, notably the 2011 Piolet d'Or, awarded with Olivier Favresse, Sean Villanueva, Ben Ditto, and Bob Shepton for an expedition to Greenland.
