Öræfasveit (]) or Öræfi (previously called Litlahérað) is a western region in Austur-Skaftafellssýsla, Iceland. It lies between Breiðamerkursandur and the river Skeiðará, east of the village of Kirkjubæjarklaustur and South, West and East of the Öræfajökull volcano. It has been a part of the municipality of Hornafjörður since 1998. In the Middle Ages, this region was called Hérað or Litlahérað, but was deserted in the wake of the 1362 eruption of Öræfajökull and the subsequent flooding of the region. After these events the region was simply called Öræfi (wilderness/desolation).
