Ust

UST most commonly refers to the University of Santo Tomas, a private Roman Catholic research university in Manila, Philippines. It was established in 1611 by Miguel de Benavides, then Archbishop of Manila, and is widely regarded as the oldest existing university in Asia. The university is administered by the Dominican Order and offers programs across the arts and humanities, natural and social sciences, medicine, engineering, business, and education.

The campus in Manila features historic architecture, including the iconic Main Building, and the university maintains traditions tied to Catholic higher education. UST has a long-standing role in Philippine education and culture and operates a range of research centers, libraries, and affiliated hospitals and teaching clinics, such as the University of Santo Tomas Hospital.

In other contexts, UST can denote other universities or organizations that use the same initials, such as institutions naming themselves University of Science and Technology or Universitas Sains dan Teknologi. Because of this, the meaning of UST is often clarified by context.
