Mr William Collins is a fictional character in the 1813 novel Pride and Prejudice by Jane Austen. He is the distant cousin of Mr Bennet, a clergyman and holder of a valuable living at the Hunsford parsonage near Rosings Park, the estate of his patroness Lady Catherine De Bourgh, in Kent. Since Mr and Mrs Bennet have no sons, Mr Collins is also the current heir presumptive to the Bennet family estate of Longbourn in Meryton, Hertfordshire, due to the estate being entailed to heirs male. Mr Collins is first introduced during his visit to Longbourn. His dull-witted character is in parallel to another 'Austen' character, Mr. Rushworth, from Mansfield Park. Mr Collins is also somewhat comparable to the Shakespearean character, Malvolio, from Twelfth Night.

Pride and Prejudice is the second novel by English author Jane Austen, published in 1813. A novel of manners, it follows the character development of Elizabeth Bennet, the protagonist of the book, who learns about the repercussions of hasty judgments and comes to appreciate the difference between superficial goodness and actual goodness.
