The Board of WPA is made up of 18 members from five different regions across the globe. Also known as zonal representatives, they act as mediators between the association's member societies and the governing bodies of WPA. They are elected every three years by the WPA General Assembly during the WPA World Congress of Psychiatry to work with member societies in a defined geographical zone.

Board members play a key coordinating role within their WPA Zones. They encourage collaboration among WPA Member Societies in their zone and stimulate their participation in WPA activities; support the dissemination of WPA-related information and educational materials; and assist the executive committee in ascertaining the needs of member societies and the ways in which these needs can be met.
