Kerið (; also Kerith or Kerid) is a volcanic crater lake located in the Grímsnes area in south Iceland, along the Golden Circle. It is one of several crater lakes in the area, known as Iceland's Western Volcanic Zone, which includes the Reykjanes peninsula and the Langjökull Glacier, created as the land moved over a localized hotspot, but it is the one that has the most visually recognizable caldera still intact. The site is a popular area for tourists in Iceland.

== Geology == Kerið is the northernmost of four craters situated along an 800-meter fissure called the Tjarnarhólar [ˈtʰja(r)tnarˌhouːlar̥] row. It was formed through explosive volcanic activity (classified as a maar) and is elliptical, measuring approximately deep, wide, and across. The wall of the crater consists of basalt, formed following the cooling of lava, and scoria. Sources differ as to when the explosion occurred that created the crater, ranging from 6,420 years ago to 9,000 years ago.
