Damasus II, né Poppo (d. August 9, 1048), Pope from July 17 to August 9, 1048, was the second of the German pontiffs nominated by Henry III, Holy Roman Emperor. His original name was Poppo, and he was bishop of Brixen when the emperor raised him to the papacy.

The shortness of his reign led to rumors that he had been poisoned; it is more likely he died of malaria.
