Long Wharf is a waterfront district and neighborhood of the city of New Haven, Connecticut, United States.
Its location can be defined as the area stretching inland from the west side of New Haven Harbor northwest to Union Avenue, west to Hallock Avenue and Cedar Street, and north to the Oak Street Connector and I-95 (up to the Q-Bridge). It is located directly south of downtown New Haven and the Wooster Square neighborhood. Interstate 95 bisects the neighborhood from the southwest to northeast; it intersects with Interstate 91 in the extreme northeast section of the neighborhood. The Oak Street Connector/Route 34 also connects with Interstate 95 in the selfsame section.
The area is called "Long Wharf" because there was once a wharf here that projected out of the juncture of Water St. and Union Ave. that continued to grow into New Haven Harbor until it finally reached a length of 3/4ths of a mile, making it the longest wharf in the country. Along it stood the Customs House, warehouses and other businesses. It was destroyed in the late 1940s-early 1950s when the harbor was partially filled in to construct Interstate Highways 91 and 95, dramatically moving the waterfront and creating this district.
