The College of the Immaculate Conception of Concordia (Spanish: Colegio de la Inmaculada Concepcion de la Concordia), commonly known as Concordia College Manila, is a private Catholic basic and higher education institution run by Daughters of Charity of Saint Vincent de Paul in Paco, Manila, in the Philippines. The college was founded in 1868. The institution is affiliated with DC-SLMES (St. Louise de Marillac Educational System).

Colegio de la Inmaculada Concepcion de la Concordia was established by Doña Margarita Roxas de Ayala by converting her three-and-a-half-hectare villa, the La Concordia Estate in Paco, Manila, into a school. She requested eight nuns from the Daughters of Charity from Spain to come to the Philippines to administer the school. They arrived on May 3, 1868, and operated the free school or Escuela Pia. Sixty students enrolled and were taught religion, good manners, reading and writing, simple arithmetic, culture, and arts like sewing, embroidery, cooking, needlecraft and household work. The medium of instruction was Spanish.

In 1868, the school officially adapted a new name, Colegio de la Inmaculada Concepcion de la Concordia, the same year that it became the Central House of the Daughters of Charity in the Philippines.

Significant periods in the development of the Concordia College, such as the Philippine Revolution of 1896 and the American era, brought about education reform.
