The Psychology Coalition at the United Nations (PCUN) is composed of representatives of psychology and psychology-related organizations that are Non-Governmental Organizations (NGOs) accredited at the United Nations (UN) and those affiliated with United Nations departments, agencies and missions.

Members of the PCUN collaborate in the application of psychological principles, science, and practice to global challenges of the UN agenda. The PCUN seeks to accomplish this overarching aim through advocacy, research, education and policy and program development guided by psychological knowledge and perspectives to promote human dignity, human rights, decent work, psychosocial well being and positive mental health.
