Ateneo de Davao University is a private Catholic basic and higher education institution run by the Philippine Province of the Society of Jesus in Davao City, Davao del Sur, Philippines. It was established in 1948 when the Jesuits took over the administration of the diocesan school, St. Peter's Parochial School. The Jesuits renamed the school to "Ateneo de Davao" after taking control. At that time, the Jesuits named all the schools that they were opening "Ateneo." Ateneo de Davao is the seventh school in the country to be named as Ateneo by the Jesuits. The university has five undergraduate schools, namely the School of Arts and Sciences, School of Business and Governance, School of Engineering and Architecture, School of Education and the School of Nursing. The graduate programs are under these units as well. The College of Law is a separate unit within the university. The university also runs a grade school and high school, both Junior High and Senior High.

John Berchmans, SJ was a Jesuit scholastic and is revered as a saint in the Catholic Church.
