Saoirse-Monica Jackson is the actress voicing Professor Sybill Trelawney in the new Harry Potter full-cast audiobook editions, according to Pottermore Publishing, Audible, and Harry Potter's official site. The casting announcement places her in a 200-plus performer ensemble for the series, which launches on November 4, 2025.
Who plays Trelawney
Saoirse-Monica Jackson takes on the role of Professor Trelawney in the audiobook adaptation, bringing a new interpretation to the Hogwarts divination teacher best known for dramatic prophecies and a distinctive, ethereal presence. The announcement was part of the final wave of cast reveals for the full-cast audio project.
Why the casting matters
This is not the same as Emma Thompson's film performance of Professor Trelawney, which remains the best-known screen portrayal of the character. The audiobook version is a separate production designed to expand the story with a large ensemble cast, immersive sound design, and a more theatrical listening experience.

Background context
Professor Trelawney is one of the series' most recognizable secondary characters, known for her divination lessons, her dramatic predictions, and her connection to the prophecy about Harry Potter and Voldemort. The audiobook casting leans into that theatrical quality by placing her in a production built around performance-rich voice work rather than screen presence.
"Saoirse-Monica Jackson as Professor Trelawney" was among the headline casting announcements for the full-cast audio editions.
Why listeners care
Fans often search cast names because audiobook performances can change how a familiar character feels, especially in a role as stylized as Professor Trelawney. A distinctive voice performance can make the character feel more mysterious, comic, or dramatic, and that is exactly the kind of change a full-cast audio production is designed to deliver.
