PACOS TRUST is a community-based organisation actively involved in improving the quality of life of indigenous communities since 1987. Formally registered in 1997 under the Trustees Ordinance of Sabah, Malaysia, PACOS TRUST sees itself as an organization that strives to empower communities through systematic building and strengthening of community organizations, which can act collectively on their own.

PACOS supports community organisations in 12 districts involving 25 geographical areas, with each organization determining and implementing its own area plan and work programme. It has 60 personnel; almost all are working in their own community but also contributing to the organization by being part of different ad-hoc committees as resource persons depending on their skills and knowledge.
