Keira Christina Knightley (pronounced /ˌkɪərəˈnaɪtlɪ/; born 26 March 1985) is an English film and television actress. She began her career as a child and came to international prominence in 2003 after co-starring in the films Bend It Like Beckham and Pirates of the Caribbean trilogy.

Knightley has appeared in several Hollywood films and earned nominations for the Academy Award for Best Actress and Golden Globe Award for Best Actress for her role as Elizabeth Bennet in Joe Wright's 2005 adaptation of Jane Austen's novel Pride and Prejudice. Two years later she again was nominated for the Golden Globe Award for Best Actress, as well as the BAFTA Award for Best Actress in a Leading Role for her performance in Atonement.

In 2008, Forbes claimed Knightley to be the second highest paid actress in Hollywood (behind Cameron Diaz), having reportedly earned $32 million in 2007, making her the only non-American person on the list of highest paid actors or actresses. However, Knightley has denied such a figure.
