Oona Castilla Chaplin (born 4 June 1986) is a Spanish-Swiss actress and dancer.
Born in Madrid, Spain, Chaplin also grew up in Switzerland. From the age of 15 she attended Gordonstoun School in Scotland and later attended RADA in London. Chaplin's parents are American actress Geraldine Chaplin and Chilean cinematographer Patricio Castilla. Her namesake is her maternal grandmother Oona O'Neill, American playwright Eugene O'Neill's only daughter and British comedian and filmmaker Charlie Chaplin's fourth wife.
Her first screen appearances was on the British drama series Spooks in 2007. She had a minor part in the James Bond movie Quantum of Solace. She had a recurring role as Marnie Madden on the BBC drama series The Hour, and she appeared in the BBC series Sherlock as John Watson's girlfriend Jeanette.
In an interview with The Daily Telegraph that was published on August 11, 2011, Chaplin confirmed she had secured a role in the second season of Game of Thrones. This was later suggested to be Jeyne Westerling. However, her character introduces herself as Talisa Maegyr rather than Jeyne when she first appears in "Garden of Bones." It was later revealed that the original plan had been for Chaplin to play Jeyne, but the character was dramatically changed in rewrites. Eventually George R.R. Martin himself suggested renaming her and came up with her character's new name.
