Mandaluyong was only a barrio of Sta. Ana de Sapa, part of the district of Paco, Province of Tondo. When the Spaniards found the place, they changed its name to San Felipe Neri in honor of the Patron Saint of Rome.

Mandaluyong, the heart of the "Golden Triangle" (Manila, Makati and Quezon City), has finally emerged as a veritable boom city. It is one of the leading business and industrial centers in the country. Today, the "New Tiger" of Metro Manila is making an unprecedented giant leap to progress.

Mandaluyong lies on a heart-shaped 26 sq. km. of land, 7 km. southeast of Manila, and 6 km. west of Pasig. To the south lies Makati, to the northwest, San Juan, and to the northeast, Quezon City. Thus, Mandaluyong is located at the very center of Metro Manila. With this geographical advantage, it has in recent years emerged as a veritable boomtown, the leading business and industrial mecca of the country.

Mandaluyong, municipality in the northern Philippines, on the island of Luzon, in Rizal Province.

Mandaluyong is an important industrial and residential area of Manila. It is located on metropolitan Manila's semicircular outer beltway (locally referred to by its acronym, EDSA).
