Ardo (orArdonus, possibly short forArdabastus; died 720/721) is the last attestedking of the Visigoths, reigning from 713 or 714 until his death in 720 or 721.^[1][2][3] TheVisigothic Kingdom was already severely reduced in power and area at the time he succeededAchila II, and his dominions probably did not extend beyondSeptimania and present-dayCatalonia, due to theArab conquests of the previous three years.

Ardo is only recorded in one Visigothic regnal list as reigning for seven years.^[4][5] As of 716 the Arabs crossed over thePyrenees and invadedNarbonensis, the last province under Gothic control.^[4] Over the next three years Ardo probably defended what remained of the Visigothic kingdom and he "may have gone down fighting like his predecessor" after the Arabs tookNarbonne and before they conquered all that remained of the old kingdom.^[4][6]

If Ardo is to be identified with Ardobastus, then he survived the invasion and negotiated a treaty, wherein he representedChristians as the Count of the Christians of al-Andalus.^[7] This title would pass to a number of individuals until the tenth century at least. Other counts included: Rabî’ ibn Theodulph,^{[8]: 281–294} Abû Sa’îd al-Qûmis, (a descendant of Ardabastus)^[9] and Mu’âwiya ibn Lubb.^[10]
