Cobble Hill is a neighborhood in the New York City borough of Brooklyn, USA. Bordered by Atlantic Avenue on the north, Hicks Street to the west, Smith Street on the east and Degraw Street to the south, Cobble Hill sits adjacent to Boerum Hill and Brooklyn Heights with Carroll Gardens to the south. The Cobble Hill Historic District covers the majority of the neighborhood but only extends east to Court Street, not Smith. The neighborhood is part of Brooklyn Community Board 6.

The area is historically Italian and is served by two commercial main streets - Court and Smith Streets. Family-run shops are Cobble Hill's biggest attraction; Italian meat markets (such as Staubitz Meat Market on Court St.) and old time barber shops mixing with trendy new restaurants. Smith Street is known as Brooklyn's "Restaurant Row" due to the large number of eateries and watering holes that opened on the street during the late 1990s and early 2000s. With a second blossoming of specialized bars along the corridor in the late 2000's, Smith Street became an upscale weekend nightlife destination. Cobble Hill Park, at the intersection of Congress and Clinton Streets, was reconstructed in 1989 and reflects the brick and stone character of this tree lined neighborhood. Cobble Hill is also renowned for its private Italianate style brownstone and brick row houses. Many of these buildings were remodeled according to regulations dictated by the New York City Landmarks Preservation Commission as the gentrification of the eastern and southern borders of this designated Historic District took hold.

Until the 1970s, Cobble Hill and Carroll Gardens were, together, known as "South Brooklyn", even though they are in the northwest portion of the modern borough, because they were south of Atlantic Street (now Atlantic Avenue), which was the southern boundary of the City of Brooklyn (now Brooklyn Heights and Downtown Brooklyn) during part of the 19th century. In 1844 the Cobble Hill Tunnel was dug in Atlantic Street so trains could avoid climbing the hill. The neighborhood is served by the Bergen Street IND Culver Line (F G) subway station. This station has an unused lower level that has in the past been used for express service.

There are three schools in Cobble Hill. Public School 29, also known as the John M. Harrigan School, is located on Henry Street and has one of the best records in the city for extracurricular activities. Also, the building on Baltic Street that formerly housed Intermediate School 293 (which closed in 2005 due to poor performance) now contains two 6-12th grade schools, with the Brooklyn School for Global Studies occupying the top floor, and the School for International Studies on the bottom floor.

Congregation Baith Israel Anshei Emes is located at 236 Kane Street in Cobble Hill. It is currently the oldest continuously operating synagogue in Brooklyn.

St. Paul's church at Court and Congress Streets was designed and built about 1838, allowing the claim that this church is the oldest Catholic church in continuous use in Brooklyn. The steeple was added in the 1860's, and other enlargements were made. The church fronts on Court Street, the chapel and former rectory on Congress Street.
