The Great Seal of the Navajo Nation was designed by Mr. John Claw, Jr., of Many Farms, Arizona, and was officially adopted by the Navajo Tribal Council on January 18, 1952, by resolution CJ-9-52.

The Great Seal had forty eight projectile points or arrowheads symbolizing the Navajo Nations protection within the forty eight states (as of 1952). Since then, two points have been added to represent the entire fifty states of the United States. The opening at the top of the three concentric lines is considered the East. The lines represent the rainbow and sovereignty of the Navajo Nation. The rainbow never closes on the Nation's sovereignty. The outside line is red, the middle line is yellow and the inside line, blue. The yellow sun shines from the east on the four sacred mountains, Sisnaajinii, Tsoodzi[, Dook'o'osl77d, and Dib4 Ntsaa. Yoo[gaii, Doot['izhii, Diichi[i, and Baashzhinii are the sacred mountain ceremonial stones.

Two cornstalks with pollen symbolizes the sustainer of Navajo life. A horse, cow, and sheep, located in the center, symbolizes the Navajo livestock.

The Navajo Nation Flag, designed by Jay R. DeGroat of Mariano Lake, New Mexico, was officially accepted by the Navajo Tribal Council on May 21, 1968, by resolution CMY-55-68.

The copper color outlines the present reservation, with the original Treaty of 1868 in dark brown. In the cardinal points on the tan field are the Sacred Mountains. A rainbow, symbolizing sovereignty arches over the Navajo Nation. In the center of the reservation, a circular symbol depicts the sun above two green stalks of corn between which are three animals representing the Navajo livestock economy, a traditional Hogan and a more modern type of house. Between the hogan and house is an oil derrick symbolizing the resource potential of the Nation, and above this are represented the wild fauna of the reservation. At the top, nearest to the sun, the modern sawmill symbolizes the progress and industry currently characteristic of the Nation's development.
