Theodoric II, Teodorico in Spanish and Portuguese (died 466) was the eighth King of the Visigoths from 453 to 466.

Theoderic II, son of Theodoric I, obtainsthe throne by killing his elder brother Thorismund.

English historian Edward Gibbon writes that "he justified this atrocious deed by the design which his predecessor had formed of violating his alliance with the empire."

In late 458, Western Roman Emperor Majorian enters Septimania to attack Theodoric and reclaim the province for the empire.

Majorian defeats Theodoric at the Battle of Arelate, forcing the Visigoths to abandon Septimania and withdraw west to Aquitania.

Under the new treaty with the Romans, the Visigoths have to relinquish their recent conquests in Hispania and return to federate status.

However, after the assassination of Majorian in 461, Theodoric recaptures Septimania and invades Hispania again.

Theodoric is himself murdered in 466 by his younger brother Euric, who succeeds him to the throne.
