Stuðlagil Canyon (; also transliterated as Studlagil) is a basalt column canyon located in the Jökuldalur valley in East Iceland. Known for its towering hexagonal basalt formations and vivid turquoise river, the canyon gained international attention after the flow of the Jökulsá á Dal (Jökla) River was reduced due to the Kárahnjúkar Hydropower Plant project. Though the canyon was physically revealed between 2006 and 2009, it remained largely unknown until its popularization by Icelandic photographer and travel writer in 2016.

thumb|alt=Stuðlagil canyon in 2016|Stuðlagil Canyon == Geological features == Stuðlagil Canyon is composed of hexagonal basalt columns formed by the slow cooling and contraction of thick lava flows during volcanic activity. This geological structure, known as basalt columns or sometimes columnar jointing, is found in several places in Iceland, but Stuðlagil is notable for the height, number, and alignment of its columns. The canyon's formations rise vertically from the riverbed, with some reaching several meters in height.
