Carlton House is a Grade II listed building in Plympton, Devon, England. Standing at 43 Fore Street, Plympton's main street, it dates to the early 19th century.
It has incised an stucco frontage with a plinth. A central panelled pilastered doorway has a moulded hood on consoles. The two-storey building has a double-depth floor plan with two rooms at the front flanking a central entrance hall, a similar layout to the nearby The Lodge at 103 Fore Street.
The building was evaluated by Time Team during their visit to Plympton in 1999. A wall belonging to an earlier incarnation of the adjacent Tan Cottage was discovered in the back garden of the property.
