Amalaric, or in Spanish and Portuguese, Amalarico, (502 – 531) was king of the Visigoths from 526 until his assassination in 531. He was a son of king Alaric II and his first wife Theodegotho, daughter of Theodoric the Great.

When Alaric II was killed fighting Clovis I, king of the Franks, in the Battle of Vouillé (507), his kingdom fell into disarray. "More serious than the destruction of the Gothic army," writes Herwig Wolfram, "than the loss of both Aquitanian provinces and the capital of Toulose, was the death of the king." Alaric had made no provision for a successor, and although he had two sons, one was of age but illegitimate and the other the offspring of a legal marriage but still a child. The older son, Gesalec, was chosen king but his reign was disastrous. King Theodoric of the Ostrogoths sent an army, led by his sword bearer Theudis, against Gesalec, ostensibly on behalf of Amalaric; Gesalec fled to Africa, and the Ostrogoths drove back the Franks and their Burgundian allies, regaining possession of "the south of Novempopulana, Rodez, probably even Albi, and even Toulose". Following the death of Clovis, Theodoric negotiated a peace with Clovis' successors, securing Visigothic control of the southernmost portion of Gaul for the rest of the existence of their kingdom.

In 522 the young Amalaric was proclaimed king, and four years later, on Theodoric's death, he assumed full royal power. His kingdom was faced with a threat from the north from the Franks; according to Peter Heather, this was his motivation for marrying Chrotilda, the daughter of Clovis. However, this was not successful, for according to Gregory of Tours, Amalaric pressured her to forsake her Roman Catholic faith and convert to Arian Christianity, at one point beating her until she bled; she sent to her brother Childebert I, king of Paris a towel stained with her own blood. It is worth noting Ian Woods advice that although Gregory provides the fullest information for this period, where it touches Merovingian affairs, he often "allowed his religious bias to determine his interpretation of the events." Peter Heather agrees with Wood's implication in this instance: "I doubt that this is the full story, but the effects of Frankish intervention are clear enough."

Childebert defeated the Visigothic army and took Narbonne. Amalaric fled south to Barcelona, where he was assassinated by his own men. According to Peter Heather, Theodoric's former governor Theudis was implicated in Amalaric's murder, "and was certainly its prime beneficiary." As for Chrotilda, in Gregory's words she died on the journey home "by some ill chance". Childebert had her body brought to Paris where she was buried alongside her father Clovis.
