Gemma Elizabeth Whelan, born in 1981 in Leeds, England, is a versatile English actress and comedian who has carved a distinctive path across television, film, and the stage. She is perhaps best known to global audiences for her commanding portrayal of Yara Greyjoy, the iron-willed and fiercely loyal sister of Theon Greyjoy, in the sprawling HBO fantasy epic Game of Thrones. Her performance in the series, which ran from 2012 to 2019, established her as a formidable presence in the landscape of prestige television and earned her a devoted fan following. Beyond her work as a dramatic actress, Whelan has also built a reputation as a sharp comedic talent, most notably through her recurring stand-up character Chastity Butterworth, a creation that highlights her improvisational skills and fearless approach to performance.

Whelan’s early career was rooted in the world of comedy and performance, where she honed her craft as a stand-up comedian and improviser. This foundation proved invaluable when she transitioned into scripted television, bringing a natural timing and physicality to her roles. Her breakout dramatic role came with Game of Thrones, but she demonstrated her remarkable range in the years that followed. She starred as Kate, the sharp-witted and long-suffering wife of the title character, in all three series of the beloved BBC sitcom Upstart Crow from 2016 to 2018, a role that showcased her impeccable comedic timing alongside David Mitchell. She further expanded her dramatic repertoire with a memorable turn as Detective Eunice Noon in the critically acclaimed first series of the darkly comedic drama The End of the F***ing World in 2017, a performance that balanced deadpan humor with genuine pathos.

In 2020, she joined the third series of the hit spy thriller Killing Eve as Geraldine, the daughter of Fiona Shaw’s character Carolyn Martens, adding a new layer of emotional complexity to the show’s intricate narrative. More recently, she has taken on the leading role of DCI Kerry Henderson in the ITV police drama DI Ray, starring opposite Parminder Nagra in both its first series in 2022 and its second in 2024. This role has allowed Whelan to anchor a major network drama, demonstrating her ability to carry a series with a nuanced and compelling performance. Throughout her career, she has consistently chosen diverse and challenging parts, moving effortlessly between high-budget fantasy, period comedy, and gritty contemporary crime drama, solidifying her status as one of Britain’s most reliable and engaging performers.
