Neighbourhood Watch in the United Kingdom is the largest voluntary crime prevention movement covering England and Wales with upwards of 2.3 million household members. The charity brings neighbours together to create strong, friendly and active communities in which crime can be tackled. Neighbourhood Watch Network is the umbrella organisation supported by the Home Office to support Neighbourhood Watch groups and individuals across England and Wales.

Neighbourhood Watch groups work in partnership with the police, corporate companies with aligned values, voluntary organisations and individuals who want to improve their communities. Neighbourhood Watch aims to help people protect themselves and their properties and to reduce the fear of crime by means of improved home security, greater vigilance, accurate reporting of suspicious incidents and fostering a community spirit as well as tackling new forms of crime such as cybercrime.
