Kate Winslet's Real Name: Kate Elizabeth Winslet

Quick answer: Kate Winslet's full name is Kate Elizabeth Winslet. She was born on October 5, 1975, in Reading, Berkshire, England, and acts under her real name. Kate is her given name, not a shortened Katherine. She became an international star as Rose in Titanic (1997), won the best actress Oscar for The Reader (2008), and has won Emmys for Mildred Pierce and Mare of Easttown (Britannica; Library of Congress).

Real name and early life

Britannica's quick facts give her name in full as Kate Elizabeth Winslet. The Library of Congress name authority files her as "Winslet, Kate," with the citation "b. Oct. 5, 1975, Reading, Eng." and a later note naming Reading, Berkshire. LOC lists no variant first name, which supports Kate as her given name.

Britannica says she was raised in a family of actors and began performing young in commercials, TV, and stage plays. Her first major role was in Peter Jackson's Heavenly Creatures (1994), based on a real 1950s New Zealand murder case involving two teenage girls.

Career highlights

As Marianne Dashwood in Ang Lee's Sense and Sensibility (1995), written by Emma Thompson, she earned her first Oscar nomination. She followed it with Jude (1996) and Ophelia in Kenneth Branagh's Hamlet (1996). James Cameron's Titanic, with Leonardo DiCaprio, set box-office records and brought her a second nomination. She then chose independent films: Hideous Kinky, Holy Smoke, Quills, and Iris (2001), the last bringing another nomination.

Eternal Sunshine of the Spotless Mind (2004) and Little Children (2006) brought further nominations. Britannica says she became the youngest actress to collect five. In 2008 she reunited with DiCaprio in Revolutionary Road, directed by her then-husband Sam Mendes. She won Golden Globes for both that film and The Reader, and The Reader won her the Academy Award for best actress.

On HBO she won an Emmy and a Golden Globe for Mildred Pierce (2011). Film work followed in Contagion, Carnage, and Divergent. Her role in Steve Jobs (2015) won a Golden Globe and her seventh Oscar nomination. Mare of Easttown (2021) won her a second Emmy. She rejoined Cameron for Avatar: The Way of Water (2022) and Avatar: Fire and Ash (2025), played photographer Lee Miller in Lee (2023), and starred in HBO's The Regime (2024).
