Velasco the Basque (Arabic: بلشك الجلشقي‎, Balask al-Galaski) was the Basque ruler of Pamplona in the early 9th century. Velasco may have come to power in 799 in the uprising that overthrew the Umayyad rule in Pamplona, when Muṭarrif ibn Mūsa, probably of the Banu Qasi, was assassinated there. The contemporary Annales Regni Francorum record that "the Navarri and the Pamplonans, who had defected to the Saracens in recent years, were received back into allegiance" in 806. Velasco must be seen as a pro-Frankish leader, perhaps even a Frankish appointee.
