The Marysville Auto Plant in Marysville, Ohio, United States, is widely cited as Honda's largest single manufacturing site by output.
Honda operates a global network of manufacturing facilities where “largest” can be measured in several ways—annual vehicle production, total floor space, or workforce. This article explains where the biggest site is by common metrics and clarifies how definitions can vary over time.
Where is the largest Honda plant located?
When considering single-site production output, the Marysville Auto Plant (MAP) is located in Marysville, Ohio, just north of Columbus.
