The Ateneo de San Pablo, also referred to by the acronym AdSP, was a private, Catholic basic education institution ran by the Philippine Province of the Society of Jesus school in San Pablo City, Laguna. It was founded by the Jesuits in 1947. Initially, it only had a high school until the later establishment of a grade school in 1962. In 1978, the Jesuits closed the school after redonating to the Diocese of San Pablo the lot where the Ateneo campus was located.
