Engelberga (or Angilberga, died between 896 and 901) was the wife of Emperor Louis II and thus Carolingian empress to his death on 12 August 875. As empress, she exerted a powerful influence over her husband. Engelberga was probably the daughter of Adelchis I of Spoleto and a member of one of the most powerful families in the Kingdom of Italy at that time, the Supponids.
