Fleming-Neon also known as Neon, is a home rule-class city in Letcher County, Kentucky, in the United States.

The city was established by the Elkhorn Coal Corporation which moved into the area in 1913.

[3] A city named "Chip" existed near the community that became Fleming; it was quickly built up and served as a trading center for the nearby coal towns.

Local tradition holds that the conductor would holler instructions to people climbing aboard the train to "Knee On" and this was corrupted into the present name, replacing Chip.

In 1977, the two towns were merged into Fleming-Neon during their municipal incorporation by the General Assembly.

According to the United States Census Bureau, the city of Fleming-Neon has a total area of 1.6 square miles (4.2 km2), of which 0.53 acres (2,127 m2), or 0.05%, are water.
