The City of Las Piñas (Filipino: Lungsod ng Las Piñas) (population: 532,330, 2007 Census) is a city in the National Capital Region of the Philippines. It is bounded on the north and northeast by the Parañaque City; on the east and southeast by Muntinlupa City; on the south by the Municipality of Imus, Cavite; on the southwest and west by the Municipality of Bacoor, Cavite; and on the northwest by the scenic Manila Bay. Half of its land area is residential and the remaining half is used for commercial, industrial and institutional purposes. The present physiography of Las Piñas City consists of three zones: Manila Bay, coastal margin and Guadalupe Plateau.

The city is bisected by Real (Spanish for Royal) Street, also known as the Alabang-Zapote Road . It forms part of the Maharlika Highway which spans the whole country. The Alabang–Zapote Road connects the South Luzon Expressway which passes through Muntinlupa City in the east to the Coastal Road along Manila Bay.

The Coastal Road, despite its name, is a major tollway which runs the southern length of Metro Manila's shoreline with Manila Bay. It is an important artery for people commuting to and from Las Piñas City and Cavite to Manila.
