Harriet Marston Slater was born on February 18, 1994, in Leicester, England. While specific details about her early schooling remain private, her path to the stage was set early through a strong foundation in classical theater. She moved to London to pursue her acting ambitions, eventually securing a spot at the prestigious Royal Academy of Dramatic Art (RADA). She graduated from their three-year BA (Hons) Acting course in 2017, honing the vocal skills that would later define her career.

Before her breakout roles, Slater spent years building a portfolio through student productions and minor television parts. These early appearances included guest spots in British medical dramas like Doctors and Casualty, which served as essential stepping stones into the industry. During this time, she focused on mastering various accents and developing a versatility that allowed her to play characters ranging from contemporary urbanites to historical figures. Her dedication to the craft during these formative years laid the groundwork for her eventual success in major streaming series. [edit]

Slater's professional trajectory accelerated after graduating from RADA in 2017. Her feature film debut came in 2018 with the horror-thriller The Prodigy, followed by a role in the BBC drama Lucky Man. However, it was her casting as Jenny Cooper in the DC Universe series Pennyworth in 2019 that marked her true breakthrough. She appeared in the show's first three seasons until its conclusion in 2022, earning critical praise for her chemistry with co-star Jack Bannon and a dedicated fanbase.

In 2021, she expanded her reach in international cinema with a role in the psychological thriller The Last Letter from Your Lover. By 2023, her ascent was recognized when Tatler named her a Bright Young Thing. She continued to secure major roles, starring in the MGM+ period drama Belgravia: The Next Chapter in 2024 and the horror film Tarot. In 2025, she landed the lead role of Jax Hunter in the Starz prequel Outlander: Blood of My Blood, utilizing her Scottish accent skills to acclaim from fans. Most recently, she reprised her role as Jax Hunter in the 2026 horror sequel Fall 2: Deadpoint, where critics noted her performance remained a standout element despite mixed reviews for the film.
