Чильдеберт II (c.570<ref>Хільдеберт, A. C. Murray,The Oxford Dictionary of Late Antiquity, ed. Oliver Nicholson, Vol. I, (Oxford University Press, 2018), 320.</ref>–595) was the Merovingian king of Австралія (яка включала Прованс at the time) from 575 until his death in 595, as the eldest son of Сігебер I, А король Бургундії from 592 to his death, as the adopted son of his uncle Guntram.

He was then only five years old, and during his long minority the power was disputed between his mother Брунхільда and the nobles.
Чиліпер I, king at Париж, and the Burgundian king Guntram, sought an alliance with Childebert, who was adopted by both in turn.<ref name=van/> Because Guntram was lord of half of Марсель, the district of Provence became a centre of a brief dispute between the two.
Guntram allied with Dynamius of Provence, who instigated the canons of the Diocese of Uzès to elect their deacon Marcellus, as bishop in opposition to their already-elected bishop Йовінус, a former governor of Provence. While Jovinus and Theodorus, Bishop of Marseille, were travelling to the court of Childebert, Guntram had them arrested. Dynamius, meanwhile, blocked Gundulf, a duke of an important senatorial family and Childebert's former domesticus, from entering Marseille on behalf of Childebert. Eventually he was forced to yield, though he later arrested Theodore again and had him sent to Guntram. Childebert replaced him in Provence by Nicetius (585). Despite his revolt, Childebert formally restored Dynamius to favour on 28 November 587.
Heir, king and war leader
But with the assassination of Chilperic in 584 and the dangers occasioned to the French monarchy by the expedition of Gundoald in 585, Childebert threw himself unreservedly into the arms of Guntram. By the Анделотський договір of 587, Childebert was recognised as Guntram's heir, and with his uncle's help he quelled the revolts of the nobles and succeeded in seizing the castle of Woëwre. Many attempts were made on his life by Фредегунд, wife of Chilperic, who was anxious to secure Guntram's inheritance for her son Clotaire II. Childebert II had relations with the Візантійська імперія, and fought on several occasions in the name of the Імператор Моріс, проти Лангобарди in Італія, with limited success.<ref>Ian Wood, Королівства Меровінг, (Longman, 1994), 167-168.</ref>
On the death of Guntram in 592, Childebert annexed the kingdom of Burgundy, and even contemplated seizing Clotaire's estates and becoming sole king of the Franks. However, he and his young wife Faileuba were poisoned to death in 595. He had two minor sons: the older, Федеберт II, inherited Austrasia with its capital at Metz, and the younger, Теудерік II received Guntram's former kingdom of Burgundy, with its capital at Orléans.
