Makati (/məˈkɑːti/ ^ⓘ mə-KAH-tee; Tagalog pronunciation: [mɐˈkaː.t̪ɪ]), officially the City of Makati (Filipino: Lungsod ng Makati), is one of the highly urbanized cities that make up Metro Manila, the capital region of the Philippines. Makati is a center for finance, commerce, culture, the arts and fashion, academics, and as the home to numerous diplomatic missions and embassies, is the center for the country's international diplomacy. With 432 high-rises and skyscrapers, Makati has the largest skyline in the Philippines, 138 of which exceed 100 m (328 ft). According to the 2024 census, Makati has a population of 309,770 people.

The city covers about 18.17 square kilometers (7.02 sq mi), making it one of the smallest cities in the Philippines in terms of land area. It is bordered by Mandaluyong to the north, Taguig to the east, Pasay to the south, and the capital city of Manila to the west.

Because of people working in the central business district, Makati's daytime population swells to 3.2-4.2 million people.

As of 2023, Makati has an estimated GDP per capita of ₱1,778,002, making it the highest GDP per capita in the Philippines.

The name of Makati originates from the Tagalog word kati, meaning "[of the] low tide" or "[of the] ebb tide", attributing to the tidal movements of the adjacent Pasig River. It originated from a misheard response in 1571 by locals to then-Governor-General Miguel López de Legazpi, who recorded the place's name as "Macati" after hearing them exclaim “Makati na! Kumakati na!” (transl. "It's low tide! The tide is ebbing!"). Used during the colonial eras, "Macati" was the historical Hispanized spelling of "Makati;" it was also spelled as "Macaty" or "Macali." Alternatively, the word may also mean "itchy", attributed to the lipang kalabaw plant (Dendrocnide meyeniana) that once grew in the area.

Until 1914, it was named San Pedro [de] Macati, a name stylized in Spanish after its patron saint, Saint Peter. The name was chosen by his namesake, Spanish captain Pedro de Brito, for his encomienda named Hacienda Pedro (now part of the present-day city), and in honor of Rev. Fr. Pedro de los Montes, who built the namesake church now known as Saints Peter and Paul Parish Church. Alternatively, it was wholly spelled in its Filipinized or Tagalized form, "San Pedro [de] Makati." The name was colloquially shortened to “Sampiro” by residents, referring to both the then-town and the church.

Parts of Makati were once subject to the pre-Hispanic Kingdom of Namayan, whose capital is now in the Santa Ana district of Manila.

Parts of Makati became a visita of the then-town of Santa Ana de Sapa in 1578, during the Spanish colonial era. In 1589, Captain Pedro de Brito, then an aide to the Spanish Army chief of staff, purchased a land encompassing the present-day Poblacion with a public bid of 1,400 pesos, and established his encomienda named "Hacienda Pedro". In 1608, he and his wife Ana de Herrera donated half of land to the Jesuits, with the condition of building a church in honor of his namesake, Saint Peter the Apostle, and endowed 14,000 pesos for its construction. The church, later known as San Pedro Macati Church, was completed in 1620.
