Cobble Hill is a Brooklyn neighborhood in New York City. Bordered by Atlantic Avenue on the north and Degraw Street to the south, Cobble Hill sits adjacent to Boerum Hill and Brooklyn Heights with Carroll Gardens to the south. The area was historically Italian and is centered around two main roads - Court and Smith Street. Family-run shops are Cobble Hill's biggest attraction; Italian meat markets 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 that opened on the street during the late 1990s and early 2000s. Cobble Hill is also renowned for its private brownstone residences and brick row houses.

Until the 1970s, Cobble Hill and Carroll Gardens were, together, known as "South Brooklyn," even though they are in the northwest portion of the borough, because they were south of the original settlement in what is now Brooklyn Heights and downtown Brooklyn.

Cobble Hill is the "Co" in the meta-neighborhood BoCoCa which is an almalgamation of three names, Boerum Hill, Cobble Hill, and Carroll Gardens.
