Metropolitan Manila (Filipino: Kalakhang Maynila [kalakˌhaŋ maɪˈnilaʔ]), commonly shortened to Metro Manila and formally the National Capital Region (NCR; Filipino: Pambansang Punong Rehiyon), is the capital region and largest metropolitan area of the Philippines. Located on the eastern shore of Manila Bay, the region lies between the Central Luzon and Calabarzon regions. Encompassing an area of 636.00 km (245.56 sq mi) and with a population of 13,484,462 as of 2020, it consists of sixteen highly urbanized cities: Manila—the capital city—Caloocan, Las Piñas, Makati, Malabon, Mandaluyong, Marikina, Muntinlupa, Navotas, Parañaque, Pasay, Pasig, Quezon City, San Juan, Taguig, and Valenzuela, along with one independent municipality, Pateros. As the second most populous and the most densely populated region in the Philippines, it ranks as the 7th most populous metropolitan area in Asia and the 6th most populous urban area in the world.

The region is the center of culture (including arts and entertainment), economy, education, and the government. Designated as a global power city, the region exerts a significant impact on commerce, finance, media, art, fashion, research, technology, education, and entertainment both locally and internationally. It is home to all embassies in the Philippines, making it an important center for international diplomacy in the country. Its economic power establishes the region as the country's premier center for finance and commerce. The region accounts for 36% of the gross domestic product (GDP) of the Philippines. Greater Manila is the fourth largest ASEAN country subdivision by GDP, after Singapore, and the Jakarta, and Bangkok metropolitan regions.

Muntinlupa (Tagalog: [mʊntɪnˈlupɐ]), officially the City of Muntinlupa (Filipino: Lungsod ng Muntinlupa), is a highly urbanized city in the National Capital Region of the Philippines. According to the 2024 census, it has a population of 552,225 people.

It is bordered on the north by Taguig, to the northwest by Parañaque, by Bacoor and Las Piñas to the west, to the southwest by Dasmariñas, by San Pedro to the south, and by Laguna de Bay, the largest lake in the country, to the east. From high above, the city of Muntinlupa has many large, green patches, which is unusual for Metro Manila. Because of these green patches, Muntinlupa earned the name "Emerald City" by the tourism establishment and also known as the "Gateway to Calabarzon" as it is the southernmost city of the National Capital Region.

Parañaque, officially the City of Parañaque (Filipino: Lungsod ng Parañaque, Tagalog pronunciation: [paɾaˈɲäke̞]), is a highly urbanized city in the National Capital Region of the Philippines. According to the 2024 census, it has a population of 703,245 people.

It is bordered to the north by Pasay, to the northeast by Taguig, to the southeast by Muntinlupa, to the southwest by Las Piñas, and to the west by Manila Bay. Like the rest of Metro Manila, Parañaque experiences a tropical climate with only two distinct seasons, wet (July to September) and dry (October to June). The city enjoys an annual rainfall of 1,822 millimeters (71.7 in) and an average daily maximum temperature of 34.4 °C (93.9 °F).

The Metropolitan Manila Development Authority (MMDA; Filipino: Pangasiwaan sa Pagpapaunlad ng Kalakhang Maynila) is a government agency of the Philippines responsible for constituting the regional government of Metro Manila, comprising the capital city of Manila, the cities of Quezon City, Caloocan, Pasay, Mandaluyong, Makati, Pasig, Marikina, Muntinlupa, Las Piñas, Parañaque, Valenzuela, Malabon, Taguig, Navotas and San Juan, and the municipality of Pateros.

The MMDA is under the direct supervision of the Office of the President of the Philippines. It performs planning, monitoring and coordinative functions, and in the process exercises regulatory and supervisory authority over the delivery of metro-wide services within Metro Manila without diminution of the autonomy of the local government units concerning purely local matters.
