What state is directly south of Nebraska?

The state that is directly south of Nebraska is Kansas. This is affirmed by the geographical layout of the United States, where Nebraska shares its southern border with Kansas. Understanding U.S. geography and the locations of individual states is essential for recognizing their relative positions. Each state has neighboring states that can be identified by their geographical proximity; in this case, Kansas lies directly to the south, while the other options do not share a border with Nebraska to the south.

Iowa is to the east, Minnesota is to the northeast, and South Dakota is directly to the north of Nebraska. Hence, Kansas is the correct answer, as its location directly aligns it to the south of Nebraska.
