East Avenue is a major street in the Diliman area of Quezon City, Philippines.

[2] It is also home to the Quezon City Hall Complex on the avenue's junction with Elliptical Road.

After crossing the Sen. Miriam P. Defensor-Santiago Avenue, the western section is dominated by more government establishments, particularly medical institutions, including East Avenue Medical Center, Bangko Sentral ng Pilipinas Security Plant Complex, Philippine Heart Center, Laguna Lake Development Authority headquarters, National Kidney and Transplant Institute, and the Quezon City Hall Complex.

Previously called Silangan Avenue (Tagalog for east),[3] the avenue forms the eastern boundary of the formerly proposed 400-hectare (990-acre) Diliman Quadrangle within the former Diliman Estate, also known as Hacienda de Tuason, purchased by the Philippine Commonwealth government in 1939 as the new capital to replace Manila.

[4] It was originally planned as the new city's Central Park, housing the new national government buildings (the new presidential palace, Capitol Building, and Supreme Court complex) within the 25-hectare (62-acre) elliptical site now known as the Quezon Memorial Circle, according to the Frost Plan.
