Atma Jaya Yogyakarta University

Atma Jaya Yogyakarta University is a university in Yogyakarta, Indonesia, which was affiliated with the Universitas Katolik Indonesia Atma Jaya in Jakarta. It was established on 27 September 1965 by the Yogyakarta branch of the Atma Jaya Catholic University Institute of Indonesia. The founders of the University were R.A. Soehardi, A.J. Liem Sioe Siet A., Sutijoso, Oey Liang Lee and Leo Sukoto.

Originally an extension of the Universitas Atma Jaya in Jakarta, it became an independent University under the auspices of the Slamet Rijadi Foundation on 31 August 1973. The University originally borrowed classrooms from the IKIP (Teaching and Education Institute) Sanata Dharma, now the Universitas Sanata Dharma, until the University's own campus buildings, located at Mrican Baru Street, were finished in 1980.

Growing student numbers led to the Faculty of Engineering and the Administration department being moved to a new building in Babarsari Road in 1990, in conjunction with the celebrations of the silver anniversary of the founding of the University. In 1995, the Economics Faculty and the Postgraduate Program moved into a new building beside the existing building in Babarsari Road. In 2005 a new building was built adjacent to the Faculty of Engineering and the Administration department to host the Faculty of Social and Political Science. The University also acquired the former BHS Bank building to host administrative department. A new integrated library 4 story building has been build next to the Faculty of Social and Political Science building. It will host library and Information Systems Center. The Library building is officially open in a mass led by Mgr. Ignatius Suharyo (Arch Bishop) on October 2009.

The motto of the University is "Servien in lumine veritatis"
(serving in the light of truth).

The Rector for 2007-2011 period was Prof. Dr. Dibyo Prabowo, M.Sc with 3 vice rectors Dr. A. Koesmargono (Academic), Mr Luddy Indra Purnama (Administrative and Finance), and Mr A. Siswanto as acting (temporary) vice rector for Students, Alumni, and Cooperation. In early 2009, Mr. A. Siswanto was replaced by Mr Hestu Cipto Handoyo, the position vice rector for Students, Alumni, and Cooperation became permanent (no longer temporary/acting). On 19th August 2009 Prof. Dr. Dibyo Prabowo, M.Sc. died after a week in hospital due to a heart attack. Dr. A. Koesmargono was appointed as acting rector. Eventually, Dr. Koesmargono is elected as rector after defeating 2 other candidates (Dr. Gunarto the dean of Law Faculty and Dr Kusumadmo from the Faculty of Economics) in an election. Dr Koesmargono will serve as rector for the remainder of Prof. Dibyo Prabowo's term (until 2011). Professor Yoyong Arfiadi is appointed vice rector to fill position left vacant by Dr. Koesmargono.
