Mia Honey Winslet Threapleton (born 12 October 2000) is an English actress. The daughter of actress Kate Winslet and painter-filmmaker Jim Threapleton, she made her film debut with a small part in the period drama A Little Chaos (2014). On television, she co-starred with her mother in the episode "I Am Ruth" (2022) of the anthology series I Am..., and starred in the period drama series Dangerous Liaisons (2022) and The Buccaneers (2023). She had her first lead role in a feature film in the black comedy The Phoenician Scheme (2025).
Her parents divorced in 2001. Her name Mia means "mine" in Italian and has no family significance associated with it, her parents just found it beautiful. She has four half-siblings; actor Joe Anders (born 2003) from her mother's second marriage to film director Sam Mendes, another half-brother (born 2013) from her mother's third marriage to Edward Abel Smith, and two half-sisters from her father's second marriage. Her maternal grandmother worked as a nanny and waitress, and her maternal grandfather was a struggling actor who took labouring jobs to support the family. Her paternal grandfather, Edward ‘Ted’ Threapleton, is a Royal Air Force Officer. She has Irish and Swedish ancestry through her mother. Her maternal great-grandparents were both actors and ran the Reading Repertory Theatre Company. Her step-father, Edward Abel Smith, is the former head of marketing promotion and astronaut experience at Virgin Group and the nephew of the company's co-founder, English business mogul Richard Branson. After marrying Winslet in 2012, Smith became a stay-at-home dad helping her raise her children.
Threapleton's parents decided to keep her and her siblings out of the spotlight when they were growing up. She grew up between New York City and England. In 2010, she moved with her mother and half-brother from New York City to England in order to avoid paparazzi, and since 2013 they have lived in West Wittering, Sussex.
During her childhood, she aspired to become a marine biologist; however, this dream was soon abandoned upon the realization that she struggled with mathematics and science. Around the age of thirteen, she first openly expressed her desire to pursue acting, confiding in her mother as the first person to hear of her new ambition. Threapleton actively searched for talent agents and explored open audition opportunities through casting websites. Using her father's surname as her stage name helped Threapleton slip under the radar during auditions when she started acting because casting directors did not associate her with her famous mother. Winslet said that having a different surname was great for Threapleton's initial job. "The people who cast her had absolutely no idea that she was my daughter. And of course, that was my biggest fear and most important for her self esteem," she said.
In 2022, she starred with her mother Kate Winslet in "I Am Ruth", an episode of the Channel 4 anthology series I Am..., whose dialogues were entirely improvised, and also featured her half-brother Joe Anders portraying her character's brother. The episode won the Best Single Drama BAFTA, with Winslet winning the Best Actress BAFTA.
