Immaculate Conception Academy (ICA) located at 10 Grant Street, Greenhills, San Juan, Metro Manila is a non-stock, non-profit elementary and secondary school owned by the Missionary Sisters of the Immaculate Conception (MIC) a Canadian founded congregation of women religious by Delia Tetreault. ICA caters to Chinese-Filipino young students: whereas its neighboring school, XAVIER, a Jesuit run institution admits Chinese-Filipino boys.

ICA traces its foundation in 1935-1936 when the Chinese families in Binondo requested the MIC sisters to open a school so that their children who have been baptized in the Catholic Church could be followed up in the practice or living out of their faith. The School moved seven times from one place to anohter to accomodate its growing population. At the invitation of the Jesuits who were then building Xavier School sometime in 1958 in the newly opened subdivision in Greenhills, the MIC sisters also constructed a building so that by 1960 the building was ready to receive the Chinese-Filipino students from ICA-Intramuros which continued to operate the elementary department and kindergarten. In 1975 ICA-Intramuros was fused with ICA-Greenhills.

Originally, ICA was considered an Anglo-Chinese School with a double curriculum (Chinese and English). In 1945, ICA became a Filipino school offering the Chinese Language Arts Program as an essential part of the curriculum. ICA undertook the accreditation process in Sy 1983-84: received full accredited status in 1986. It was re-accredited in 1989-1994. At present ICA's student population numbers about 3,200.
