Immilla (also Emilia, Immula, Ermengard or Irmgard) (born c.1020, died January 1078) was a member of the Arduinici dynasty.
Immilla was the daughter of Ulric Manfred II of Turin and Bertha of Milan. Her older sister was Adelaide of Susa.
Her first husband was Otto of Schweinfurt, whom she married c.1036.
With her first husband, Otto, Immilla had five daughters:
After Otto's death in September 1057, Immilla married again (c.1058). Her second husband was Ekbert I of Meissen.
With her second husband, Ekbert I, Immilla had the following children:
In 1067, shortly before his death, Ekbert I attempted to repudiate Immilla in order to marry Adelaide, daughter of Otto I, Margrave of Meissen. After Ekbert's death in 1068, Immilla spent some time at the imperial court with her niece Bertha, before returning to Italy. It is possible that she acted as regent for her young son, Ekbert II, at this time.
Immilla died in Turin in January 1078. She is sometimes said to have become a nun before her death.
