Selbyville is a town in Sussex County, Delaware. The population was 1,645 as of the 2000 census. Selbyville is part of the Seaford, Delaware Micropolitan Statistical Area. The town was founded way back in 1778, and was originally known as Sandy Branch due to its location at the head of the St. Martin's River. In 1842 a man by the name of Sampson Selby began marking packages for delivery to his country store, Selby-Ville. By 1918 the town had changed its name as it grew to become one of the largest distributors of strawberries in all of New England. One of the town's largest employers is Mountaire Farms, a poultry company. The town is also home to Mumford Sheet Metal Works, which once held the record for having made the world's largest frying pan. The biggest schools here are Selbyville Middle School and Showell Elementary School.
