William H. Long House, Historic residence in Greenville, North Carolina.

The William H. Long House is a two-story brick-veneer dwelling with a hipped roof intersected by gable-roofed wings at the sides and rear. A monumental pedimented portico and a porte cochere, both carried on paired Tuscan columns, mark the Classical Revival design. It stands at 200 East 4th Street in Greenville and has housed law offices since a renovation around 1980.

William Henry Long, Greenville's mayor from 1901 to 1903, built the house in 1917–1918. Around 1980 it was renovated to house law offices, and in 1982 it was added to the National Register of Historic Places.

The house's Classical Revival detailing includes a monumental pedimented portico and a porte cochere, both carried on paired Tuscan order columns. William Henry Long, Greenville's mayor from 1901 to 1903, had it built as his residence; since about 1980 the former home has housed law offices.

The building is visible from the street and easily located in downtown Greenville. Since it now operates as law offices, interior access may be limited for visitors.

William Henry Long, who built the house, was mayor of Greenville from 1901 to 1903; the house was listed on the National Register of Historic Places in 1982, two years after its conversion into law offices.
