The flag of Cincinnati is the municipal banner of the city of Cincinnati, Ohio, in the United States. The design was selected in an 1896 contest. It was formally adopted on June 15,
The blue waves represent the Ohio River, upon which the city was founded. The red "C" in the center stands for Cincinnati and a red buckeye leaf rests atop the letter to symbolize the State of Ohio. The center of the C features most of the Seal of Cincinnati, including the winged rod (commerce), serpents (wisdom), scales (justice), and a sword (authority and power). The motto on the flag, Juncta Juvant, is derived from a Latin phrase meaning "Unity Assists".
