Brooklyn police precincts and their neighbors join together annually in August for National Night Out (NNO), an annual community-building campaign that promotes police-community partnerships and neighborhood camaraderie.

Millions of neighbors take part in NNO across thousands of communities from all 50 states, U.S. territories and military bases worldwide on the first Tuesday in August. Texas and select areas celebrate the first Tuesday in October. 

Neighborhoods host block parties, festivals, parades, cookouts and various other community events with safety demonstrations, seminars, youth events, visits from emergency personnel, exhibits and more.

The event was first introduced in August 1984 through an already established network of law enforcement agencies, neighborhood watch groups, civic groups, state and regional crime prevention associations and volunteers across the nation. 

The first annual National Night Out involved 2.5 million neighbors across 400 communities in 23 states. This year, 70 precincts in New York participated, including 23 from Brooklyn.
