Ela of Salisbury, 3rd Countess of Salisbury 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.

William Longespée, 3rd Earl of Salisbury was an Anglo-Norman nobleman, primarily remembered for his command of the English forces at the Battle of Damme and for remaining loyal to his half-brother, King John. His nickname "Longespée" is generally taken as a reference to his great physical height and the oversized weapons that he used.
