Established in 1985, Chief Officers 3rd Sector (CO3) is a leading membership-based organisation that focuses on supporting, developing and connecting Third Sector leaders in Northern Ireland.

We have a growing membership base of over 800 Third Sector leaders. Our members range from leaders of some of the largest charities and social enterprises through to small community and faith-based groups.

We use the term Third Sector to describe the breadth of our members’ work. Members work across all policy areas and connect to all government departments. Our members offer considerable expertise, services and innovation. Our members lead organisations that contribute resources and investment in public services, employ tens of thousands of people and have a considerable asset base to help strengthen the economy.
