Jan Fredrik Ericsson (14 March 1975 in Sundsvall, Sweden – 6 August 2010 at K2, Pakistan) was a Swedish mountaineer and extreme skier.
He grew up in Umeå in the northern part of Sweden, but spent most of his time in Chamonix, in the French Alps.
In 2005, Ericsson and his Norwegian friend Jörgen Aamot made an attempt to ski the coveted Laila Peak (6069 m) in Pakistan, but bad conditions forced them to turn around at 5950 m. They were the first people who ever skied down the mountain.
On 6 August 2010, Gerlinde Kaltenbrunner joined Ericsson and his partner Trey Cook on the way to the summit of K2, leaving Camp 4 (8000 m) at 1:30 a.m.
Between 6:30 and 7:00, just below the Bottleneck, Cook turned back due to cold hands that had been frostbitten weeks earlier while establishing the team's Camp 3.
