Romanos (Ρωμανός) II Porphyrogennitos (Πορφυρογέννητος) was a Byzantine and Eastern Roman emperor of the 10th century. He was not actively involved in military campaigns but left them in the capable hands of Nikephoros Phokas. His son was the illustrious Basil II. It is presumed he died from poisoning by his wife, Theophano. His reign was ultimately good, but not one he was too involved in.
