Saint Mildrith, also Mildthryth, Mildryth and Mildred, (Old English: Mildþrȳð) (born c. 660, died after 732), was a 7th- and 8th-century Anglo-Saxon abbess of the Abbey at Minster-in-Thanet, Kent.

Mildrith was the daughter of King Merewalh of Magonsaete, an area similar to the present day Herefordshire, a sub-kingdom of Mercia.

Her mother was Domne Eafe (also sometimes named as Saint Eormenburga),[1] herself a great-granddaughter of Æthelberht of Kent, and as such appearing in the so-called Kentish Royal Legend.

[5] Mildrith's remains, despite fierce local opposition,[6] were translated to St Augustine's Abbey, Canterbury in 1030,[1] an event commemorated on 18 May.

[9] It became a private house until 1937, when it was purchased by Benedictine nuns from St Walburga's Abbey in Eichstätt, Bavaria, as a refuge from persecution and became a dependent priory.
