Saint Irene of Tomar (Portuguese: Santa Iria) (c.635 – c.653) was a Christian who was martyred for her faith in Visigothic Portugal.

She was born into an influential family, and her parents, wishing to protect her, sent her to a convent school and a private tutor.

When Britald became depressed, Irene hastened to make it clear to him that the reason for her celibacy was that she had given herself to God as a nun.

[1] Meanwhile, her tutor, a monk named Remigius (or Remígio) made improper advances to her, and when she declined, quit and spread vicious rumors about her.

Legend says that her uncle abbot Celius had received from Christ a revelation about the true story of her niece and the location of her body.
