Skjaldbreiður is a broad shield volcano in Iceland, reaching about 1,060 metres above sea level. It formed in a large eruption roughly 9,000 years ago, and the summit crater is about 300 metres across.
The lava produced by the eruption spread southward and helped shape the landscape around Þingvellir and Þingvallavatn. The mountain is a prominent geological feature of the region and an important example of Icelandic shield-volcano formation.
