The Pilgrim's Progress (full title: The Pilgrim's Progress from This World, to That Which Is to Come) is an allegorical fiction novel written by English writer John Bunyan, originally published in 1678. The novel is predominantly of religious and theological character and consists of two main parts: the first part centers on a man named Christian who decides to leave his hometown—the City of Destruction—and go on a quest to find the Celestial City (Paradise), in order to redeem his soul; the second part of the novel focuses on Christian's wife, Chrsitiana, who also embarks on the same spiritual journey to reach Heaven.

The book is considered to be one of the most important and most published works in British religious literature and it is often regarded as the first novel ever written in English. It has been translated into more than 200 languages worldwide, and it's still relevant to this very day.

The correct date when Bunyan started and finished writing the novel is unknown; however, many literary analysts and scholars agree that most of the first part and probably a good portion of the second part were written while Bunyan was in prison and that the novel as a whole was completed either in 1675 or 1677. Bunyan was actually a Puritan preacher who didn't have a license to peach from the English Church due to his Protestant views; thus, he was imprisoned for twelve years, from 1660–1672. It was during this time that he started writing The Pilgrim's Progress, as an allegory of the Christian faith, in order to reflect on his own religious views and personal philosophy.
