Lady Catherine de Bourgh (/dəˈbɜːr/ də-BUR; née Fitzwilliam) is a character in the 1813 novel Pride and Prejudice by Jane Austen.

According to Janet Todd, Lady Catherine can be seen as a foil to the novel's protagonist Elizabeth Bennet.

Thus she and her sister are always styled as Lady Catherine and Lady Anne, as their marriages to a knight or baronet (Austen never specifies whether Sir Lewis is knighted or holds a baronetcy) and an untitled man, respectively, do not confer upon them a preferable style.

One such feature is a chimney piece in the second drawing room that is worth £800 as Mr. Collins so proudly states.

The stateliness and grandeur of Rosings Park underline the side of Mr. Darcy's background that impresses Elizabeth, although she refuses to be overawed by it.
