Denis Trento

Denis Trento (2 June 1982 – 3 May 2024) was an Italian ski mountaineer and mountain guide.

He was known for his wins at some of Europe's top mountaineering competitions, including the Adamello in 2008, the Tour du Rutor in 2009 and 2011, and the European team championship and Mezzalama Trophy in 2009. He began competing in ski mountaineering as an athlete at the Army Sports Center in Courmayeur, as a member of the Centro Sportivo Esercito.

After retiring from competition, in 2015 he became a mountain guide. He continued mountaineering, putting up speed ascents across the Aosta Valley, and beyond, including the Grandes Jorasses, Monte Rosa, Mont Blanc's Innominata ridge, and Mount Brouillard.

In 2020, alongside speed climber Filip Babicz, he climbed the Frêney pillar of Mont Blanc in a round trip ascent and descent in less than 24 hours.
