Wendreda, also known as Wendreth, was an Anglo-Saxon nun, healer, and saint, perhaps of the 7th century. She was uncertainly reported as a daughter of King Anna of East Anglia, a Christian king, which would make her a sister of Etheldreda, abbess of Ely, Sexburgha, abbess of Minster-in-Sheppey, and Ethelburga, abbess of Faremoutiers, who are all better-known saints, and a half-sister of Sæthryth, also an abbess of Faremoutiers.
