Hallbera Þorsteinsdóttir

Hallbera Þorsteinsdóttir (died 1330) was the founder and abbess of the convent Reynistaðarklaustur of the Benedictine order on Iceland.

She was the daughter of Þorsteins Halldórssonar á Hesti og Stórólfshvoli and Ingigerðar Filippusdóttur and belonged to a wealthy family. In 1295, she donated wast lands to the foundation of a convent for females of the order of Saint Benedict. This was to be one of only two convents open to females in Iceland before the reformation. She is known to have served as abbess from at least 1298. She had a close professional relationship to the Bishops of Holar, Auðunn rauði Þorbergsson and Lárentíus Kálfsson, who respected her opinion. The latter of the two dedicated several poems to her.
