The Liga ng mga Barangay, created by virtue of Section 491 of the Local Government Code of 1991, is an organization of the almost 42,000 barangays throughout the country. It was organized primarily for the purpose of determining the representation of the barangay in the sanggunian and for ventilating, articulating and crystallizing issues affecting barangay government administration and securing solutions to these concerns.

The Liga ng mga Barangay is by far the largest organization among local government associations whose members come from the grassroots.
