Mandaluyong City is one of the cities and municipalities that comprise Metro Manila in the Philippines. It is bordered on the west by the country's capital, Manila, to the north by the municipality of San Juan, to the east by Quezon City and Pasig City, and by Makati City to the south.

Mandaluyong City is located right at the center of Metro Manila. Among the many attractions in the city is the western half of the Ortigas Center, one of the major centers of business and commerce in the metropolis (the eastern half is in Pasig City). Found within the Mandaluyong portion of the Ortigas Center is the headquarters of the Asian Development Bank and the headquarters of San Miguel Corporation, the country's biggest corporation. SM Megamall, one of the largest shopping malls in the country and the EDSA Shangri-la Mall is also found here. Slightly west of Ortigas Center is the Wack-Wack Golf and Country Club, north of which is the La Salle Greenhills (LSGH), a famous all-boys high school.

Among locals, Mandaluyong City is often used in jokes pertaining to a person's mental health (e.g., a person whose mental well-being is suspect is often labelled as coming from Mandaluyong). This is because the National Center for Mental Health is found in the city. Also found in Mandaluyong is "Welfareville" a large slum-area divided in many "blocks".

Mandaluyong City got its name from the Tagalog daluy which means flowing. This is in reference to the Pasig River which flows along the southern border of Mandaluyong. In fact, Mandaluyong is among the many places in the Philippines that were named after water-related terms.

During the Spanish Period, the place was called San Felipe Neri by the Franciscan missionaries who founded the town. Mandaluyong became a city on February 9, 1994
