Lost in Austen is a four-part 2008 British television series for the ITV network, written by Guy Andrews as a fantasy adaptation of the 1813 novel Pride and Prejudice by Jane Austen. Amanda, a young woman living in modern London, enters the plot of the novel through a portal in her bathroom, to join the Bennet family and affect events, generally disastrously.

In December 2009 the show was placed at 48 in "The Top 50 TV Shows of the Noughties", a list published in The Times.
