Saint Æthelburh (died after 686) or Ethelburga, founder and first Abbess of the double monastery of Barking, was the sister of Earconwald (also spelled "Erkenwald"), Bishop of London.

Bede describes Æthelburg as "upright in life and constantly planning for the needs of her community".

The 9th century Old English Martyrology records a vision, recounted by a nun of Barking, who saw Æthelburh being drawn up into heaven by golden chains.

It survived the Great Fire and the Blitz but was extensively damaged in an IRA attack in 1993; however, it has been restored and is now a centre for international reconciliation.

[6] Other churches dedicated to Æthelburh include the Grade II listed St Ethelburga's at Great Givendale, near Pocklington in the East Riding of Yorkshire.
