Oli Green is a British actor and model whose rising career on screen has been matched by the headlines of his off-screen life. Known for roles in The Crown, A Good Person, The Mosquito Coast, and Lift — and for a modeling career with brands like Burberry and Gap — Green has built a dual career in acting and fashion since studying at the Lee Strasberg Theatre & Film Institute in New York. His relationship with actress Sienna Miller, fourteen years his senior, made him a fixture of celebrity media from early 2022 onward.
Born on January 21, 1997, Green belongs to a new generation of British talent splitting time between London and Los Angeles. His first professional acting job was a 2019 music video, and within four years he was appearing in Netflix’s flagship royal drama and starring alongside Florence Pugh and Morgan Freeman on the big screen. Despite the spotlight, he keeps his personal life deliberately private — rarely sharing details on social media and letting his work speak first.

Career
Oli Green grew up in a creative family — his father, Jonathan Green, runs an art gallery in London, and his mother, Alison Ross Green, has worked in the art world. He chose acting early and crossed the Atlantic to train at the prestigious Lee Strasberg Theatre & Film Institute in New York, where he honed his craft before pursuing it full-time.
His first professional acting job came in 2019 with John Eatherly’s “Burnout” music video. Small television roles followed: an appearance on The Bold and the Beautiful in 2020 and a part in The Mosquito Coast in 2021. The breakthrough arrived in 2023, when he played Rupert Finch — Kate Middleton’s ex-boyfriend — in two episodes of the final season of Netflix’s The Crown, and appeared as Thomas in A Good Person alongside Florence Pugh and Morgan Freeman. In 2024 he played Mollsen in the film Lift.
In parallel, Green built a successful modeling career. He was the face of Gap’s “I Am” campaign in 2017 and has worked with Burberry, modeled in shoots with Cara Delevingne and Suki Waterhouse, and in 2025 starred with his partner in a joint fashion campaign for the brand Frame. He is signed with leading agencies including Innovative Artists and United Agents.

Net Worth
Oli Green has not disclosed his income, so his net worth comes from public estimates rather than confirmed figures. One scraper-style biography source estimates it at around $1 million — a low-reliability figure that reflects his combined acting and modeling earnings rather than any verified disclosure. His income streams include television and film roles, runway and campaign modeling for major brands, and fashion partnerships. As with all such estimates, the figure should be read as an approximation.
