Ida McNeil, American broadcaster and designer of the flag of South Dakota (born 1888)

Ida McNeil was an American broadcaster and the designer of the first state flag of South Dakota. She and her husband, Dana McNeil, founded KGFX, in Pierre, South Dakota, one of the first radio stations in South Dakota, in 1927. She continued to run the station after his death in 1936 until her retirement in 1962. She has been nicknamed "Mrs. Pierre" for her work in broadcasting and "the Betsy Ross of South Dakota" for her state flag design.

The current flag of South Dakota was adopted in 1992 to represent the U.S. state of South Dakota. It consists of a field of sky blue charged with a version 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" on the bottom. The sun represents the common weather in South Dakota.
