Fifth Third Bank derives its unique and unusual name from the historical consolidation of two predecessor banking institutions that merged in the early twentieth century: The Third National Bank and The Fifth National Bank, both based in Cincinnati, Ohio. When the two banks combined their operations in 1908, the leadership team chose to blend both historic institutional names rather than discard one, resulting in the hyphenated title "Fifth Third National Bank of Cincinnati," which was later shortened for modern commercial branding. This distinctive nomenclature makes Fifth Third Bank one of the most recognizable financial institutions brand names across the American banking sector.
