Galindo Aznárez I (died 867) was Count of Aragón from 844 to 867, succeeding Galindo Garcés. He was the son of Aznar Galíndez I, who had been Count of Aragón from 809 to 820 and Count of Urgell, Cerdanya, and Conflent (820-??). Galindo Aznárez received these last three counties from his father sometime before 833, in 833 was designated count of Pallars and Ribagorza, but only governed them for a year. After a period of rule in Pamplona, he came back to Aragón in 844 to assume the Countship upon the heirless death of Galindo Garcés.
Galindo Aznárez had one son, Aznar Galíndez II, his successor.
