Cynthiana is a home rule-class city[4] in Harrison County, Kentucky, in the United States.

The first on July 17, 1862, was part of a cavalry raid into Kentucky (which stayed in the Union) by Confederate General John Hunt Morgan; the second, on June 11 and 12, 1864, resulted in Union defeat of Confederate forces during Morgan's last raid into the state.

[12] On March 2, 1997, the South Fork of the Licking River flooded, causing extensive damage in Cynthiana and neighboring communities.

In early March 2020, near the beginning of the COVID-19 pandemic in the United States, Cynthiana was reported to have the first case of the disease diagnosed in Kentucky.

Four more cases soon followed, and by March 12, most businesses, schools and churches closed in an effort to prevent further spread.

The climate in this area is characterized by hot, humid summers and generally mild to cool winters.

Until patents expired in the late 1990s, the 3M factory in Cynthiana was the only production site of Post-it notes worldwide.
