A city is one of the units of local government in the Philippines. All Philippine cities are chartered cities, whose existence as corporate and administrative entities is governed by their own specific municipal charters in addition to the Local Government Code of 1991, which specifies their administrative structure and powers. As of December 12, 2015, there are 145 cities.
Cities are entitled to at least one representative in the Philippine House of Representatives if its population reaches 250,000. They are allowed to use a common seal. As corporate entities, cities have the power to take, purchase, receive, hold, lease, convey, and dispose of real and personal property for its general interests, condemn private property for public use (eminent domain), contract and be contracted with, sue and exercise all the powers conferred to it by Congress. Only an Act of Congress can create or amend a city charter, and with this city charter Congress confers on a city certain powers that regular municipalities or even other cities may not have.
Despite the differences in the powers accorded to each city, all cities regardless of status are given a bigger share of the Internal Revenue Allotment (IRA) compared to regular municipalities, as well as being generally more autonomous than regular municipalities.
A city's local government is headed by a mayor elected by popular vote. The vice mayor serves as the presiding officer of the Sangguniang Panlungsod (city council), which serves as the city's legislative body. Upon receiving their charters, cities also receive a full complement of executive departments to better serve their constituents. Some departments are established on a case-by-case basis, depending on the needs of the city.

Cities, like municipalities, are composed of barangays, which can range from urban neighborhoods (such as Brgy. 9, Santa Angela in Laoag), to rural communities (such as Brgy. Iwahig in Puerto Princesa). Barangays are sometimes grouped into officially defined administrative (geographical) districts. Examples of such are the cities of Manila (16 districts), Davao (11 districts), Iloilo (seven districts), and Samal (three districts: Babak, Kaputian and Peñaplata). Some cities such as Caloocan, Manila and Pasay even have an intermediate level between the district and barangay levels, called a zone. However, geographic districts and zones are not political units; there are no elected city government officials in these city-specific administrative levels. Rather they only serve to make city planning, statistics-gathering other administrative tasks easier and more convenient.
