Eanflæd (19 April 626 – after 685, also known as Enfleda) is a Kentish princess, queen of Northumbria and later, the abbess of an influential Christian monastery in Whitby, England.

She is the daughter of King Edwin of Northumbria and Æthelburg, who in turn was the daughter of King Æthelberht of Kent.

In or shortly after 642 Eanflæd becomes the second wife of King Oswiu of Northumbria.

After Oswiu's death in 670, she retires to Whitby Abbey, which had been founded by Hilda of Whitby.

Eanflæd becomes the abbess around 680 and remains there until her death.

The monastery has strong association with members of the Northumbrian royal family and plays an important role in the establishment of Roman Christianity in England during that historical period.
