Quivira National Wildlife Refuge in south central Kansas, United States, includes rare inland marshes.

On January 29, 2008, Quivira NWR and Cheyenne Bottoms Wildlife Area were jointly named as one of the 8 Wonders of Kansas.

Quivira NWR is one of 29 places in the United States on the Ramsar list as a wetland of international importance.

In 1541 Spanish conquistador Francisco Vásquez de Coronado led an expedition onto the Great Plains of Kansas searching for wealth.

He spent a month with the Quivirans, the ancestors of the Wichita tribe, but returned to New Mexico without finding any gold.

Plovers, avocets, stilts, ibis, and endangered least terns nest on the refuge during the spring and summer.

800,000 geese and ducks pass through Quivira NWR en route to the Gulf Coast and Mexico.

In addition, endangered whooping cranes occasionally visit the refuge en route to their wintering grounds in Texas.
