Kjeragbolten () is a boulder on the mountain Kjerag in the eastern part of Sandnes Municipality in Rogaland county, Norway. The rock itself is a glacial deposit wedged in a large crevice in the mountain. It is a popular tourist destination and is accessible without any climbing equipment. However, it is suspended above a deep abyss. It is also a popular site for BASE jumping. The boulder is just southwest of the village of Lysebotn, just south of the Lysefjorden.

==Geology== Rogaland lies in a weak tectonic zone, allowing the river to dig into the surrounding sandstone mountain. During the several glaciations known to have occurred in Scandinavia, Norway was completely covered in glaciers. Between the glaciations, the meltwater formed and reformed the valley up to 22 times. After the last glacial period, global warming caused a rise in sea level, flooding the fjords. The boulder was deposited during this last glaciation at around 50,000 B.C. As the Norwegian Glacier melted, it was accompanied by a rebound in rock formations as the ice was removed. In Kjeragbolten's case, the rebound was faster than the rising sea level, which wedged the rock into its current position.
