A sitio (Spanish for "site") in the Philippines is a territorial enclave that forms part of a barangay.

The term is derived from the Spanish word sitio meaning "place".

During the Spanish colonial period the colonial government employed the reducción policy, allowing the remapping of various settlements.

Several far-flung hamlets were identified, named, and organized into "sitios" so that municipalities and cities could more easily be governed through the barangay system, then known as the barrio system.

[1][2] A sitio does not have an independent administration; it is established purely for organizational purposes only.
