Mayfield Cottage is a historic plantation house located near the grounds of Central State Hospital near Petersburg, Dinwiddie County, Virginia. It was built about 1750, and is a 1 1/2-story brick Colonial era mansion. The building features a jerkin-head roof and distinctive interior woodwork. It is believed to be the oldest existing brick house in Dinwiddie County. From 1885, the property was used by the hospital for its headquarters and the house was part of the hospital complex until 1969. The house was moved from its original site about .5 miles (0.80 km) to the southeast of the present site in 1969.
