Dialogo de Cecco di Ronchitti da Bruzene in perpuosito de la stella Nuova (Dialogue of Cecco di Ronchitti of Brugine concerning the New star) is the title of an early 17th-century pseudonymous pamphlet ridiculing the views of some Aristotelian philosophers on the nature and properties of Kepler's Supernova, which appeared in October 1604. It was written in crude rustic Paduan dialect, and first published in about March, 1605, in Padua. A second edition was published later the same year in Verona, and an English translation by Stillman Drake was published in 1976.

Scholars agree that the pamphlet was written either by Galileo Galilei or one of his followers, Girolamo Spinelli, or by both in collaboration, but do not agree on the extent of the contribution—if any—made by each of them to its composition.
