Emilia Fox was born in Hammersmith, London. She comes from a thespian family – her mother is actress Joanna David (née Joanna Elizabeth Hacking) and her father is actor Edward Fox; her uncle James Fox and her cousins Jack, Laurence and Lydia are also actors. She has a brother, Freddie (also an actor), and a half-sister, Lucy. She was educated at the independent Bryanston School near Blandford Forum, Dorset, where she played the cello, and at St Catherine's College, Oxford, where she read English. Her great-great-grandfather was Samson Fox, a self-made millionaire, and her great-grandmother was the actress Hilda Hanbury, sister of Lily Hanbury. Her grandfather was Robin Fox, a theatrical agent. Through Hanbury, she is related to the Terry family of actors. Fox first appeared as Georgiana, the sister of Colin Firth's Mr. Darcy, in the 1995 television adaptation of Pride and Prejudice, followed by her role as the second Mrs. de Winter in the 1997 television adaptation of Rebecca, opposite Charles Dance. In 1998 she starred with Ben Miles in the adaptation of Catherine Cookson's The Round Tower as the young Vanessa Radcliffe, a girl from an affluent family who is forced to leave her home after becoming pregnant. Fox played Jeannie Hurst in the 2000 remake of Randall and Hopkirk.

In 2002, she starred in The Pianist as Dorota, a beautiful, blond, non-Jewish cellist who adores the playing of the Polish-Jewish pianist and composer Władysław Szpilman (played by Adrien Brody). The film was directed by Roman Polanski. In 2003, she played Jane Seymour in a two-part television biographical film about King Henry VIII. She also played the title role in Katherine Howard, directed by Robin Lefevre at the Chichester Festival Theatre in 1998.

In 2004, she joined the cast of the crime drama, Silent Witness. As of 2023, she is still in the show and has now played the role of Nikki Alexander for nineteen years. 2004 also saw her play Lady Margaret in Part 2 of Gunpowder, Treason and Plot, the mini-series about James I (James VI in Scotland) and the Gunpowder Plot. In 2005, Fox appeared in the BBC miniseries The Virgin Queen, a four-part miniseries based upon the life of Queen Elizabeth I, Fox played Amy Dudley, the first wife of Robert Dudley, played by Tom Hardy, despite appearing in only one episode, her character remains a key character in the series.

She was cast as Lynne Frederick in the 2004 film The Life and Death of Peter Sellers, which starred Geoffrey Rush in the lead role. A whole section of the film focusing on the Frederick/Sellers relationship was removed in the final edit, although she can be seen briefly in a background shot towards the end of the film. The deleted scenes with Fox can be found among the special features on the DVD release of the film.

In 2007, Fox was reunited with her Rebecca co-star Charles Dance when they starred together in the ITV1 mini-series Fallen Angel, Fox played a serial killer, Rosie Byfield, with Dance appearing as her father. The rewind format in which the show was shot traced the development of the killer streak of Fox's character. Fox and Dance had previously both appeared in ITV1's Henry VIII, but Dance's role as the Duke of Buckingham was limited, as his character was arrested for treason less than fifteen minutes into the first half, while Fox's scenes as the doomed third Queen Jane Seymour dominated the first half of the second episode. In the 2008 English language DVD re-release of the cult 2006 Norwegian animated film Free Jimmy, Fox voiced the character of "Bettina". The dialogue was written by Simon Pegg; other actors included Pegg himself and Woody Harrelson.
