Is Cobble Hill part of Brooklyn Heights?

No, Cobble Hill is its own distinct neighborhood, though it sits directly south of Brooklyn Heights and the two are frequently confused. Cobble Hill is generally bounded by Atlantic Avenue to the north, the Brooklyn-Queens Expressway to the west, and Carroll Gardens and Boerum Hill nearby. It carries its own historic district designation and identity. The neighborhoods share a brownstone character and are often shopped together by buyers, but they are separate, each with its own boundaries, feel, and market.
