The Prospect Hill Historic District is an irregularly-shaped 185-acre (75 ha) historic district in New Haven, Connecticut. The district encompasses most of the residential portion of the Prospect Hill neighborhood.^[2]

The district includes two U.S. National Historic Landmark properties which are separately listed on the National Register: the Othniel C. Marsh House and the Connecticut Agricultural Experiment Station. The district was listed on the National Register of Historic Places in 1979. In 1979, it included 238 buildings deemed to contribute to the historic character of the area.^[1]

The district is significant primarily for its architecture. It includes major collections of Queen Anne style architecture in the United States, Shingle Style architecture, Colonial Revival architecture, and Tudor Revival architecture. Numerous other styles are also represented.^[3]^: 47–51

Relationship to neighborhoods

The historic district includes most of New Haven's Prospect Hill neighborhood. The district borders are drawn irregularly to exclude modern construction, and also to exclude properties fronting Whitney Avenue,^[3] which are included in the Whitney Avenue Historic District. It excludes the entire area of the Hillhouse Avenue Historic District, an area that was originally residential, and now is mostly Yale University-owned, and which included within the official neighborhood planning maps for Prospect Hill. The historic district also excludes the Edgerton historic district, the New Haven portion of which has been included in the official neighborhood planning maps for Prospect Hill.

Among other exclusions, the district excludes Yale University's relatively modern buildings on Science Hill. It excludes several Yale graduate student housing facilities (the Whitehall Apartment Complex, the Mansfield Apartments, and the Esplanade Apartments), while at 352 Canner Street, the district includes four dormitory buildings of the Yale Divinity School.

The district extends to the south to include historic houses that are now Yale offices along the west side of Prospect Street south of Hillside Place.^[5]
