The United Nations Congress on Crime Prevention and Criminal Justice is the world's largest and most diverse gathering of policy-makers, practitioners, academia, intergovernmental organizations and civil society in the field of crime prevention and criminal justice. The Congresses have been held every five years since 1955 in different parts of the world, dealing with a vast array of topics. They have made considerable impact in the field of crime prevention and criminal justice and influenced national and international policies and professional practices. The Congresses provide a forum for (a) the exchange of views between States, intergovernmental and non-governmental organizations and individual experts representing various professions and disciplines; (b) the exchange of experiences in research, law and policy development; and (c) the identification of emerging trends and issues in crime prevention and criminal justice.
 
The 14th UN Congress on Crime Prevention and Criminal Justice will be held from 7 to 12 March 2021 in Kyoto, Japan. The UN General Assembly has formally decided on these dates (A/DEC/74/550 B), which had been recommended by the Commission on Crime Prevention and Criminal Justice, as the preparatory body of the Crime Congress. There will be pre-Congress consultations on 6 March 2021. The 14th Congress was originally scheduled to take place in Kyoto, Japan, on 20-27 April 2020, and postponed, due to the worldwide COVID-19 pandemic.
 
The overall theme, agenda items and the topics for the workshops of the Fourteenth Congress were determined by the United Nations General Assembly in its resolution 72/192. The Commission on Crime Prevention and Criminal Justice also advanced preparations for the Fourteenth Congress through its resolutions submitted for adoption by the Assembly in 2018 and 2019.
