The Clermont County flag was designed in 2002 by Melanie Gilliam, a local graphic artist. Her design depicts Clermont County as the gateway to freedom, prosperity, and equality. The stylized "C" in the flag design represents the county proximity to the Ohio River, as well as the sweeping progress of growth and the promise of her bright future. The circle of fourteen golden stars symbolizes each of the townships and the unified way their governments work together. Clermont County was established in 1800, and takes its name from the French word meaning "clear mountain."
