The public sector, sometimes referred to as the state sector or the government sector, is a part of the state that deals with either the production, ownership, sale, provision, delivery and allocation of goods and services by and for the government or its citizens, whether national, state, or local.

Social democrats tend to favor a medium-sized public sector that is limited to the provision of universal programs and public services. Economic libertarians and minarchists favor a larger private sector and small public sector with the state being relegated to protecting property rights, creating and enforcing laws and settling disputes, a "night watchman state".
