Aznar Galíndez I (also Asnar Galí) (died 839) was a Basque Count of Aragon and Conflent from 809 and Cerdanya and Urgell from 820.
Aznar succeeded Aureolus as count of the valley of the River Aragón on the latter's death in 809.
He was installed by king Louis the Pious (a son of emperor Charlemagne), and remained a Frankish vassal.
In 820, he was overthrown by his son-in-law García the Bad, supported by Íñigo Arista's Navarrese forces.
He took refuge in the Vasconia that remained suzerain to the Franks, and was appointed count in Urgell and Cerdanya.
