The Ateneo de Iloilo – Santa Maria Catholic School (AdI–SMCS) (simplified Chinese: 怡朗亚典耀圣母学校; traditional Chinese: 怡朗亞典耀聖母學校; pinyin: Yílǎng Yàdiǎnyào Shèngmǔ Xuéxiào; Pe̍h-ōe-jī: Î-lóng A-tián-iāu Sèng-bió Ha̍k-hāu), is a private, Jesuit, Catholic, Chinese-Filipino Basic Education school run by the Philippine Province of the Society of Jesus in Iloilo City, Philippines.

Ateneo de Iloilo is a K-12 school and its curriculum includes Chinese language, Christian Living Education, and Ignatian Spirituality programs.

The presence of this graduate school is a trial balloon of Ateneo de Iloilo's plan to become a higher education institution in the future and to eventually become a university.

The Jesuits came to Iloilo City in 1953 after being expelled from China by the Communists, and continued their apostolic work in the local Chinese community.

With the support of the Iloilo Chinese and Filipino communities, Santa Maria Parish under the tutelage of Our Lady Queen of China was established by Fr.

When parents of the students protested the phasing-out of the high school department, the Chinese Provincial Superior reconsidered his decision.

[1] Meanwhile, a donation of 3,600 square meters of land by the Lopez family in June 1972 paved the way for the construction of a four-story concrete building in 1974 to replace the wooden one.

When SMCS celebrated its 25th founding anniversary in 1983, improvements such as the construction of additional comfort rooms, large classrooms, and a cluster of offices were undertaken.

[1] With the incessant clamor of SMCS alumni and the local Iloilo community to let their children study in a Jesuit school, a plan for expansion and transfer to a new and spacious site was initiated.

Archbishop Angel Lagdameo of the Archdiocese of Jaro and Iloilo City Mayor Jerry P. Treñas, an Ateneo de Manila alumnus, witnessed the MOA signing which formalized the establishment of the Ateneo de Iloilo – Santa Maria Catholic School, a Jesuit school separate from the parish.

[1][2] Groundbreaking rites for the construction of a four-story building (Phase 2) worth P200 million for the use of the Grade School Department and the Administration were held on June 1, 2013.

[1][3][4] The school has totally transferred to the new site in Barangay San Rafael, Mandurriao District, Iloilo City, in 2017, with 2,100 students and 200 faculty and staff.
