Quercus margarettae (spelling variants include Quercus margaretta, Quercus margarettiae, and Quercus margaretiae), the sand post oak or dwarf post oak, is a North American species of oak in the beech family. It is native to the southeastern and south-central United States from Virginia to Florida and west as far as Texas and Oklahoma. There are historical reports of the species growing in New York State, but it has not been seen there in years.
