Mareen Duvall (1625–1699) was a French Huguenot and an early American settler.

He was born Marin duVal, at Nantes, France in 1625 and arrived in the Province of Maryland on August 28, 1650. He received a patent from the first proprietors of the Maryland Colony, the Calvert family on that day for La Val, named after his family's estate in the County of Laval situated between County of Maine, Duchy of Brittany, Duchy of Normandy and Duchy of Anjou in France, on the south side the South River in Anne Arundel County, Maryland.

He became quite prosperous and his Middle Plantation in Davidsonville, Maryland and La Val were "as luxurious and courtly as any of the manors of the English gentry."

He died in 1699 and his third and final wife, Mary Stanton, administered his substantial estate. Duvall had purchased sizeable tracts of land, including Catton, later known as Belair as well as owning Middle Plantation in Davidsonville, Maryland. Combined, he owned several thousand acres in Anne Arundel and Prince George's Counties. It is believed that the original house called Middle Plantation was located somewhere along Rutland Rd.
