British actress T’Nia is best known for her starring role in Netflix’s supernatural horror series ‘The Haunting of Bly Manor’ which was the worldwide number one show on Netflix for 3 weeks.  She received a nomination for a Critic’s Choice Super Award and her performance received widespread acclaim, with Vanity Fair praising her standout performance and The Hollywood Reporter remarking that “Miller shines” in the pivotal fifth episode of the season.  In 2023 she was re-united with Bly Manor director Mike Flanagan in 'The Fall of the House of Usher', also on Netflix, in which she played Victorine LaFourcade, the doomed illegitimate daughter of a ruthless businessman. 

In 2025 she makes her debut in the third season of hit Sky Atlantic drama series 'Gangs of London', joining the cast as the formidable new Mayor of London, determined to wreak havoc on the gangs. 

She is also recognisable for her work as the dynamic ‘Celeste’ on the BBC/HBO drama series ‘Years and Years’ in which she starred alongside Emma Thompson and Rory Kinnear.  She won 'Best Actress in a TV Series' at the National Film Awards in 2021 for this role.  The series also won three RTS Awards and was nominated for three Critics Choice Awards.

In 2023 she played Cecilia Dennison, sister to the UK foreign secretary, in Netlix's hit political drama 'The Diplomat'. In 2022 she starred in the Amazon Prime sci-fi thriller series 'The Peripheral', from the creators of Westworld, as arch protagonist Cherise Nuland. In 2021 T'Nia had major roles in Spanish adventure thriller ‘La Fortuna’ and Apple TV’s new sci-fi drama ‘Foundation’.

Other notable TV credits include a memorable turn on Netflix's critically acclaimed series, ‘Sex Education’, Amazon’s sci-fi drama ‘The Feed’ and the multiple award winning ‘Obey’ (also Amazon) which won ‘Best Cinematography’ at the TriBeCa Festival.  She has also appeared in Netflix’s teen drama series ‘Free Rein’, ITV crime dramas ‘Hatton Garden’ and ‘Marcella’ as well as season 9 of ‘Doctor Who’ on the BBC and C4’s award winning series ‘Cucumber’ and its spin-off series ‘Banana’ (both currently showing on Netflix). 

Outside of acting, she is an activist and a passionate proponent of natural hair in the Black community.  She is also a strong advocate for the Black Lives Matter movement. 

T’Nia’s native accent is neutral British. Being London born, she can swing into a London or Cockney accent and Jamaican comes easily due to her parentage. Her American accent is also faultless having used it for two major roles in La Fortuna & Foundation.
