The flag of South Dakota represents the U.S. state of South Dakota with a field of sky blue charged with a version (in navy blue on white) of the state seal in the center, surrounded by gold triangles representing the sun's rays, surrounded in turn by inscriptions in gold sans-serif capitals of "SOUTH DAKOTA" on top and "THE MOUNT RUSHMORE STATE" (the state nickname) on the bottom. The inscription on the bottom was "THE SUNSHINE STATE" before it was changed in 1992.
The official pledge of the South Dakota flag is "I pledge loyalty and support to the flag and state of South Dakota, land of sunshine, land of infinite variety." The only protocol to the state flag pledge is that it does not either replace or preempt the Pledge of Allegiance to the flag of the United States.
