The U.S. state containing the city of Valentine, named for Congressman E. K. Valentine, is Nebraska.
Valentine is located in north-central Nebraska and serves as the county seat of Cherry County. The city was named for Edward Kimble Valentine, a Republican politician who represented Nebraska in the U.S. House of Representatives from 1879 to 1885. He later served as sergeant at arms of the United States Senate.
The community developed in connection with the railroad, which helped establish settlements and transportation links across the Great Plains. Today, Valentine is known as a gateway to the scenic Sandhills and the Niobrara National Scenic River, a popular destination for canoeing, tubing, and wildlife watching.
A likely mix-up comes from nearby Midwestern states such as Iowa, Missouri, and Kansas. Valentine’s namesake was born in Iowa Territory, but the city itself is in Nebraska—and the congressman represented Nebraska when he held federal office.
