McElhone has a brother, Damon (by Taylor), and two half-brothers, Nicholas and Alex (by Taylor).

She studied acting at the London Academy of Music and Dramatic Art.

She made her television debut in 1990, again credited as "Natascha Taylor", in Television South's adaptation of the Inspector Wexford story An Unkindness of Ravens.

She appeared the following year, again as "Natascha Taylor," in the series Bergerac as Louise Calder, a rebellious daughter of very wealthy parents. She appeared in two episodes of the Dennis Potter television miniseries Karaoke.

McElhone's first major box-office role, and an early role where she was credited as her new stage name, came with Surviving Picasso (1996), with co-star Anthony Hopkins. One of her most successful films to date has been The Truman Show (1998) with Jim Carrey. She had leading roles opposite Brad Pitt in The Devil's Own (1997), Robert De Niro in Ronin (1998) and George Clooney in Solaris (2002).

McElhone has narrated several audiobooks (alone, or in collaboration with other narrators) including Figuring by Maria Popova, Picasso by Arianna Huffington, Amok by Sebastian Fitzek, and several children's stories by Matt Haig.

McElhone married plastic surgeon Martin Hirigoyen Kelly on 19 May 1998. The couple lived in Fulham, south-west London. They had three sons, the third born five months after Kelly's death.

On 20 May 2008, 43-year-old Kelly was found slumped in the doorway of his family's home by a fellow doctor, who had him rushed to Chelsea and Westminster Hospital. He could not be revived and died one day after his 10th wedding anniversary. A postmortem exam revealed the cause of death to have been dilated cardiomyopathy.

After her husband's death, McElhone continued to write letters to him, sometimes documenting the daily trivia of life but also dealing with how she and their young children were coping with their loss. These letters and diary entries formed the basis of her book After You: Letters of Love, and Loss, to a Husband and Father, published in July 2010.
