Who plays the character Sophie Baek, Benedict's love interest, in Bridgerton Season 4?

Yerin Ha takes on the pivotal role of Sophie Baek, Benedict Bridgerton's central love interest, in the fourth season of Netflix's hit series Bridgerton. This highly anticipated season draws its inspiration from Julia Quinn's third novel in the Bridgerton series, "An Offer From a Gentleman," which famously presents a Regency-era twist on the classic Cinderella (Review) narrative. Viewers were introduced to this captivating storyline when Bridgerton Season 4 premiered in two parts, with the first episodes releasing in late January 2026 and the conclusion in late February 2026.

Sophie Baek's character is a fan favorite from the books, known for her resilient spirit despite her humble circumstances. As the illegitimate daughter of an earl, Sophie is relegated to life as a maid in her stepmother's household, a stark contrast to the opulent world of the Ton. Her fateful encounter with Benedict occurs at a masquerade ball, where she attends disguised as the mysterious "Lady in Silver," unaware that he is the Bridgerton (Review) brother who will eventually steal her heart. The showrunners intentionally changed Sophie's surname from Beckett, as it appears in the novel, to Baek as a nod to Yerin Ha's Korean heritage, enriching the character's background and reflecting the series' commitment to diverse representation.

Yerin Ha, an accomplished Korean-Australian actress, brings this beloved character to life. Prior to joining the world of Bridgerton, Ha was recognized for her roles in other significant productions, including the Paramount+ series "Halo" and the HBO prequel series "Dune: Prophecy." Her casting as Sophie Baek has been met with considerable excitement, as she embodies the strength and vulnerability that make Sophie such a compelling figure within the Bridgerton universe, offering audiences an engaging and fresh interpretation of a cherished literary romance.
