Ereleuva (born before AD 440, died ca. 500?) was the mother of the Ostrogothic king Theodoric the Great. She is often referred to as the concubine of Theodoric's father, Theodemir, although historian Thomas Hodgkin notes "this word of reproach hardly does justice to her position. In many of the Teutonic nations, as among the Norsemen of a later century, there seems to have been a certain laxity as to the marriage rite..." That Gelasius refers to her as regina ("queen") suggests that she had a prominent social position despite the informality of her union with Theodemir.
