The Missal of the Academy of Sciences (Portuguese: Missal da Academia das Ciências) is a notable Portuguese 17th-century Roman Pontifical codex, profusely illuminated by Estêvão Gonçalves Neto.
Originally commissioned for João Manuel de Ataíde, at the time Bishop of Viseu, its iconographic programme reflects the ideas of the Counter-Reformation. Bishop Ataíde had it deposited in the library of the Convent of Our Lady of Jesus in Lisbon and, since 1834, it has belonged to the collection of the Lisbon Academy of Sciences.
It is widely considered the finest specimen of Portuguese miniature, and has been called by historian Joaquim Veríssimo Serrão a "veritable masterpiece of the national genius".
