Constance I (Italian: Costanza; 2 November 1154 – 27 November 1198) was the queen of Sicily from 1194 until her death and Holy Roman Empress from 1191 to 1197 as the wife of Emperor Henry VI.
As queen regnant of Sicily, she reigned jointly with her spouse and later with her infant son, the future Holy Roman Emperor Frederick II. She is particularly notable for her actions against her own family, the Norman kings of Sicily; she played an important role in the end of the Hauteville presence in Sicily.
