Muhammad Ali known as Ali Sadpara[1] (born February 2, 1976; missing since 5 February 2021)[2] is a Pakistani mountaineer. He was part of the team that successfully achieved the first ever winter summit on Nanga Parbat in 2016.[3] Both his teammates, Alex Txikon and Simone Moro, have gone on record stating that they could not have done it without Sadpara's brilliance. He had successfully climbed four eight-thousanders in a calendar year and a total of eight in his career.[4]

Sadpara and his 21-year-old son Sajid Sadpara, who had climbed K2 in 2019, teamed up with Icelandic mountaineer John Snorri Sigurjónsson[5] and Chilean mountaineer Juan Pablo Mohr Prieto[6] for a joint K2 ascent, leaving the highest camp on the evening of February 4, 2021. Sajid had to descend due to a technical issue, leaving the others at the Bottleneck, close to the summit. His father, Snorri, and Mohr kept climbing up, but they didn't come back by night as planned. A rescue mission with two army helicopters was organized on February 6. The three climbers are still missing.[7]
