Madeira is a city in Hamilton County, Ohio, United States. The population was 9,487 at the 2020 census. A residential suburb of Cincinnati, Madeira has a small downtown and some light industry.

Madeira was largely laid out in 1871. Before this time the place was known as a post town, and was named for John Madeira who owned a large tract of land in the vicinity.
