The flag of the Comanche Nation has a blue and red background superimposed with the gold Comanche seal. The blue half of the background appears to the left side of the flag while the red half is to the right.
The seal consists of a gold outline of a circle inscribed with the words “Comanche Nation” at the top and “Lords of the Southern Plains” at the bottom. A silhouette of a Comanche mounted on a horse and carrying a pole bearing the flag appears on the red portion of the background. The seal also features a wavy line down the center between the blue and red halves of the background.
