Ayala Malls Trinoma is a large shopping mall in Quezon City, Philippines, owned by property development firm Ayala Land. Opened on May 16, 2007, the mall is located on the east side of Epifanio de los Santos Avenue in Quezon City, giving significant market competition to the nearby SM North EDSA as one of the largest malls in Metro Manila. It is also one of two malls that will be serving Ayala Land's Vertis North township, which is located beside the mall, along with a new lifestyle block mall Ayala Malls Vertis North, similar to Greenbelt in Makati, which was also developed by Ayala Malls.

Epifanio de los Santos Avenue, commonly referred to by its acronym EDSA, is a limited-access circumferential highway around Manila, the capital city of the Philippines. It passes through 6 of Metro Manila's 17 local government units or cities, namely, from north to south, Caloocan, Quezon City, San Juan, Mandaluyong, Makati, and Pasay.
