Sybill Trelawney On Audible: Voice Actor And Performance
Saoirse-Monica Jackson, the acclaimed Irish actress renowned for her role in Derry Girls, voices Professor Sybill Trelawney in Audible's full-cast audio editions of the Harry Potter series. This casting was officially announced by Pottermore Publishing and Audible on October 21, 2025, marking a significant update to the immersive audiobook productions that began rolling out with Harry Potter and the Philosopher's Stone on November 4, 2025.
Character Background
Professor Sybill Trelawney is the eccentric Divination teacher at Hogwarts School of Witchcraft and Wizardry, introduced in J.K. Rowling's Harry Potter and the Prisoner of Azkaban, published in 1999. Known for her misty glasses, shawls, and vague prophecies, she descends from the famous seer Cassandra Trelawney and delivers the pivotal prophecy about Harry Potter and Lord Voldemort during an interview with Albus Dumbledore.
Her teaching style emphasizes tea leaves, crystal balls, and inner eyes, often frustrating students like Harry, Ron, and Hermione, who view Divination as a woolly subject. Despite her pretensions, Trelawney's rare genuine visions, such as the one predicting Voldemort's return, cement her importance in the series, spanning from 1980 when she joined Hogwarts until sharing duties with Firenze in later books.
