Makati's 1st congressional district is one of the two congressional districts of the Philippines in the city of Makati. It has been represented in the House of Representatives of the Philippines since 1998. The district consists of barangays in western Makati, namely Bangkal, Bel-Air, Carmona, Dasmariñas, Forbes Park, Kasilawan, La Paz, Magallanes, Olympia, Palanan, Pio del Pilar, Poblacion, San Antonio, San Isidro, San Lorenzo, Santa Cruz, Singkamas, Tejeros, Urdaneta, and Valenzuela. It is the location of the Makati Central Business District and the Makati City Hall. It is currently represented in the 20th Congress by Monique Lagdameo of the Makatizens United Party (MKTZNU).
The district was created in 1995 when Makati was granted cityhood. However, the second district seat remained vacant during the 10th Congress due to its first representative-elect's disqualification. As a result, Makati was effectively represented as an at-large district until the 1998 elections.
