A purok (English: district[1] or zone) is an informal division within a barangay in the Philippines.

[4] A purok is typically composed of twenty to fifty or more households, depending on the particular geographical location and cluster of houses.

If created and given a mandate by an ordinance of the barangay, municipality, or city, a purok could perform government functions under the coordination and supervision of their local officials.

[6][7] On rare occasions, a purok may also be enumerated in the creation of a municipality, as in the case of Shariff Saydona Mustapha, Maguindanao where the puroks of Libutan East and Pagatin I were directly named as one of the constituent parts of the new municipality.

[8] These two puroks were later recognized as full-fledged barangays by the Philippine Statistics Authority in early 2010.
