Cincinnati's 50 largest manufacturers
The largest manufacturing firms in the Cincinnati area employ more than 64,000 local employees in the counties of Brown, Butler, Clermont, Hamilton, Warren counties in Ohio; Boone, Bracken, Campbell, Gallatin, Grant, Kenton, Pendleton in Kentucky; and Franklin, Dearborn and Ohio in Indiana. The online version of this ranking expands beyond what appears in print; another 25 manufacturers are included in our digital rankings, in addition to the 25 featured in this week's print edition. This week's List is part of a shift in our research methodology and philosophy in 2025, emphasizing more data and context for readers while better coordinating the resources available to us and our 46 sister publications under the American City Business Journals flag. We anticipate this effort will identify thousands of new local records — and cumulatively, tens of thousands of new businesses across ACBJ's footprint — this year alone. Information on The List was obtained through Cincinnati Business Courier’s research or supplied by individual firms through questionnaires that CBC could not independently verify. In case of ties, companies are ranked by total employment and then listed alphabetically if ties remain. Additionally, manufacturers that did not respond to employment surveys but were still included on this year's List are sorted by estimated total employment figures derived from Cincinnati Business Courier’s archives, annual filings with the U.S. Department of Labor and other firm-specific resources.
