St. Ignatius El Bosque (Spanish: Colegio San Ignacio El Bosque; abbreviated as SIEB) is a private Catholic primary and secondary, located in the Providencia district of Santiago, Chile.

[1] In 1931 the Society of Jesus acquired ten blocks of land in the Providencia district, intending to build a stadium for the already existent St. Ignatius Alonso Ovalle School (that was located in downtown Santiago).

Due to the advanced construction, the idea of taking the preparatory courses to the new building was purposed.

At first, the name of the new campus was supposed to be “ St. Luis Gonzaga School” but due to legal problems and the already stable reputation of the old name they kept using it but changing the name of the streets were they are located.

The principal, director, and rector is Jorge Radich Hernici, a lay person and alumnus.
