Theodemir or Theudimer (died 743) was a Visigothic comes (count) prominent in the southeast of Carthaginensis (the region around Murcia) during the last decades of the Visigothic kingdom and for several years after the Moorish conquest. He ruled seven cities in southeastern Spain, mentioned in the Treaty of Orihuela that was preserved by the Andalusian historian Ibn Adarí in the thirteenth century: Orihuela, Valentila (possibly an equivalent for Valencia), Alicante, Mula, Bigastro, Eyya (probably Ojós), and Lorca.
