Ela of Salisbury, 3rd Countess of Salisbury

Ela of Salisbury, 3rd Countess of Salisbury (1187 – 24 August 1261) was an English peeress. She succeeded to the title in her own right in 1196 upon the death of her father, William FitzPatrick, 2nd Earl of Salisbury.

Ela married William Longespée, an illegitimate half-brother of kings Richard I and John, who thus became Earl of Salisbury, in 1196. Ela held the post of High Sheriff of Wiltshire for two years after William's death, then became a nun, and eventually Abbess of Lacock Abbey in Wiltshire, which she had founded in 1229.
