The flag of Astrakhanskaya Oblast is a rectangle of sky-blue color with a golden crown in its center, consisting of a hoop with three visible leaf-formed and golden mitra, fastened with five visible arches, and decorated with pearls, with green lining. Atop of mitra there is a golden orb with a cross. Under the crown there is an oriental silver sword with golden hilt turned to the right. The width of the crown and the sword should make 1/4 of length of the flag. Width/length ratio is 2:3.
The flag features the same elements as the coat of the arms of the oblast.
