Theodelinda, Queen of the Lombards, (died 628) was the daughter of Duke Garibald I of Bavaria.
She was married first in 588 to Authari, King of the Lombards, son of King Kleph, and when he died, was allowed to pick (as her next husband, Agilulf ) his successor. She thereafter exerted much influence in restoring Athanasian Christianity (that is to say, the ancestor of modern Roman Catholicism and Eastern Orthodoxy) to a position of primacy in Italy against its rival, Arian Christianity. With a stable base in Italy thereafter, the Papacy could begin subduing those it regarded as heretics elsewhere.
