Quezon City () is the former capital (1948–1976) and the most populous city in the Philippines. Located on the island of Luzon, Quezon City (popularly known to Filipinos as QC) is one of the cities and municipalities that make up Metro Manila, the National Capital Region. The city was named after Manuel L. Quezon, the former president of the Commonwealth of the Philippines who founded the city and developed it to replace Manila as the country's capital. Quezon City is not located in and should not be confused with Quezon province, which was also named after the president.
Having been the former capital, many government offices are located in the city, including the Batasang Pambansa Complex, the seat of the House of Representatives, which is the lower chamber in the Philippine Congress. The main campuses of two noteworthy universities, the Ateneo de Manila University and the country's National University—the University of the Philippines Diliman—are located in the city.
The city lies on Guadalupe plateau which is a relatively high plateau on the northeast corner of the metropolis between the lowlands of Manila to the southwest and the Marikina River valley to the east. The southern portion is drained by the very narrow San Juan River and its tributaries to Pasig River, while running in the northern portions of the city is the equally narrow Tullahan River.
Quezon City is bordered by Manila to the southwest, by Caloocan City and Valenzuela City to the west and northwest. To the south lies San Juan and Mandaluyong City while Marikina City and Pasig City borders Quezon City to the southeast. To the north across Marilao River lies San Jose del Monte City in the province of Bulacan and to the east lies Rodriguez and San Mateo, both in the province of Rizal.
The city can be divided into a number of areas. The southern portion of the city is divided into a number of places including Diliman, Commonwealth, the Project areas, Cubao, Kamias, Kamuning, New Manila, San Francisco del Monte and Sta. Mesa Heights. The northern half of the city is often called Novaliches and contains the areas of Fairview and Lagro. Most of these areas have no defined boundaries and are primarily residential in nature.
Diliman, located at the center of southern Quezon City, is where many government offices, including the City Hall, are located. Diliman is home to schools, such as the UP Diliman, FEU-FERN College), Philippine Science High School Main Campus, Claret School of Quezon City, School of the Holy Spirit, Diliman Preparatory School and Quezon City Science High School, the regional science high school in NCR region
At Diliman's center lies the Quezon Memorial Circle, the landmark of the city where the late President Manuel L. Quezon is interred. Running around the monument is the two-kilometer Quezon Memorial Circle, also known as the Elliptical Road (R-7/C-5).
The Quezon City Hall, one of the highest city halls in the country is located along the Circle. Surrounding the city hall are spacious parks and open areas. Some of the national government agencies whose head offices are located in Diliman are the:
Surrounding the Circle are many important health centers and institutions. Along East Avenue stands the Philippine Heart Center, the East Avenue Medical Center (EAMC), the National Kidney and Transplant Institute, and the Philippine Mental Health Association. Along North Avenue is the Veterans Memorial Medical Center (VMMC) and the Philippine Health Association. The Philippine Children's Medical Center and Lung Center of the Philippines are located along Quezon Avenue (R-7).
The headquarters of NBN, RPN, IBC, PBS and the ABS-CBN Broadcast Center and GMA Network Center is also located in Diliman. The online publication covering Diliman, the Diliman Diary, is also based there.
Most of the rest of the area is residential. Some villages in this portion of Diliman are Teachers Village, U.P. Village, and Sikatuna Village. Those closer to the University of the Philippines campus such as Teachers Village and U.P. Village remain mostly residential although there are two major secondary schools in the area namely Claret School of Quezon City and Holy Family School, and many have converted spare rooms to boarding facilities for out-of-town students attending schools in the area: U.P., Ateneo, and Miriam College. The eastern edge of the Diliman area is roughly bounded by Katipunan Avenue which passes in front of Ateneo and Miriam and runs behind the U.P Diliman campus.
