Ernesto Luigi Lomasti (29 October 1959 – 12 June 1979) was an Italian mountaineer and alpino skier.
He is regarded as one of the Italian pioneers of climbing as a sport.
He died during training in the Valle d'Aosta, Arnad, in the local alpini training place called "la gruviera" (the holey cheese), he fell apparently being struck by lightning.
Ironically, he is also remembered for techniques on the Machaby pillar, in Arnaud, on May 1979.
