The Dawn of Day or Dawn or Daybreak (German: Morgenröte – Gedanken über die moralischen Vorurteile; historical orthography: Morgenröthe – Gedanken über die moralischen Vorurtheile; English: The Dawn of Day/ Daybreak: Thoughts on the Prejudices of Morality) is an 1881 book by the German philosopher Friedrich Nietzsche.

In Daybreak Nietzsche devotes a lengthy passage to his criticism of Christian biblical exegesis, including its arbitrary interpretation of objects and images in the Old Testament as prefigurations of Christ's crucifixion.

The polemical, antagonistic and informal style of this aphoristic book, when compared to Nietzsche's later treatments of morality, seems to invite a particular experience.

In this text Nietzsche is not concerned with persuading his readers to accept any specific point of view, yet there are prefigurations of many of the ideas more fully developed in his later books.

This interpretation and development of his thought were to prove errors in dogmatic teaching of Christianity that power and not divinity is the psychology of belief.
