Sanata Dharma University (Indonesian: Universitas Sanata Dharma) abbreviated as USD or Sandhar, is a private, Catholic, research, coeducational higher education institution run by the Indonesian Province of the Society of Jesus in Yogyakarta Indonesia.

"Sanatana" is a Sanskrit word that denotes that which is Anadi (beginningless), Anantha (endless) and does not cease to be, that which is eternal and everlasting.

In 1955 Catholic missionaries of the religious order of the Society of Jesus in Central Java along with lay intellectuals decided to found a teacher training college.

With the support of the Congregatio de Propaganda Fide, Father Kester, the superior of the Jesuit missionaries, united the diploma courses in Education under de Britto Foundation in Yogyakarta and in English under the Loyola Foundation in Semarang into a higher learning institution and so was born PTPG Sanata Dharma on October 20, 1955.

Since 1979 this institute has run both bachelor and diploma programs in mathematics, physics, Indonesian, English, and social science.
