Kristian Magdalon Bing (30 May 1862 – 6 July 1935) was a Norwegian jurist, author and mountaineer. He is commonly credited for re-introducing the tradition of celebrating Olsok (1897) and reviving it as an annual ceremony commemorating the death of St. Olav at Stiklestad.

In 1910, he discovered the rock carvings at Vingen in Sogn og Fjordane. These were the first rock carvings with hunting motifs discovered in Norway. He was looking for a site he where he could access hydropower from the waterfalls in the area. In 1913, Kristian Bing purchased the property.
