John Holden Greene (1777-1850) was a noted early nineteenth century architect practicing in Providence, Rhode Island. The bulk of his work dates to the late Federal period, and is mostly in the architectural style of the same name. Greene is responsible for the design of over fifty buildings built in the city between 1806 and 1830, almost half of which are still standing.
