The Provincial Administrative Organization (PAO) (Thai: องค์การบริหารส่วนจังหวัด, Acronym: อบจ.) is a devolved local government body in Thailand. It is developed from the existing provincial council which provided advices and recommendations on behalf of local people to a centrally-appointed governor. Each province (excluding Bangkok, which is administered by the Bangkok Metropolitan Administration) can has one provincial administrative organization. Due to separation of powers, a provincial administrative organization, headed by a chief executive, and a Provincial Administrative Organization Council (Thai: สภาองค์การบริหารส่วนจังหวัด) are separate bodies that work together. Local elections are held every 4 years to elect the PAO chief executives and council members, the most recent PAO local election was in 2025.
