• Year First Flown: 1917
• Designed By: Verna Keays
• Design: A blue flag that has a border of a wide red line with a white thinner border on the inside. In the middle of the flag is a white illustration of a bison with the state seal centered over it.
• Meaning: The red of the border symbolizes Native Americans and the blood of American pioneers, while the white of the border and the bison represents the sky and the mountains of Wyoming. The Bison plays a prominent role in the flag because the bison is the state mammal of Wyoming and represents the age old custom of branding. The state motto "Equal Rights" refers to the fact that Wyoming was the first U.S. state and/or territory to officially allow women's suffrage (the right to vote) in 1869.

Wyoming was admitted to the Union as one of the United States of America on July 10th, 1890. In 1916, Wyoming still did not have an official state flag and was one of the few U.S. states in this situation. A woman by the name of Dr. Grace Raymond Hebard, who was a professor of political economy at the University of Wyoming, felt that the state absolutely needed an official flag.

Hebard was also the Wyoming state regent of the Daughter of the American Revolution (DAR), and suggested that the DAR hold a contest for the design of an official Wyoming State Flag. Verna Keays, a recent graduate of the Art Institute of Chicago, submitted a design that came to her in her sleep and was awarded $20.00 when her design was deemed the contest winner. Dr. Hebard worked with Miss Keays to prefect some details of the design, and soon a bill dealing with the flag design was presented to the Fourteenth Wyoming State Legislature. On January 13th, 1917, Governor Robert D. Carey signed the bill into law and officially adopted the design as the state flag of Wyoming. In February of 1917, the State Legislature had folders depicting and explaining the new state flag distributed to every school child in the state of Wyoming.
