Þingeyrar (Thingøre in some older texts[1]) is a farm in Iceland's Northwestern Region.

It lies adjacent to the sandy coastal plain of Þingeyrasandur (or Thingøresand[1]), between the Skagi and Vatnsnes peninsulas and just northeast of lake Hóp.

Icelandic scholar and politician Björn M. Ólsen (1850–1919) was born in Þingeyrar.

Bjarni Halldórsson (c. 1703–1773), an Icelandic legal figure and theologian, spent most of his life in Þingeyrar.

One of the earliest recorded giant squid (Architeuthis dux) specimens was found washed ashore on Þingeyrasandur in 1639.
