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, 1940.
The Cincinnati city flag is defined by city ordinance:
The flag of Cincinnati shall be rectangular in shape. It shall have a white groundwork. In the center shall be a red letter "C". Extending horizontally from either side of the letter "C" shall be three wavy parallel lines of navy blue. Within the letter "C" shall be the seal of the city of Cincinnati in blue. Extending upward from a point at the top of the letter "C" and spaced equally from its center line shall be a cluster of five buckeye leaves in red. The proportional dimensions of the flag and of its various parts shall be according to the official design thereof on file in the council chamber of the city of Cincinnati.
— C.M.C. §104-3
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".
