The Davao Oriental State University is a state-funded research-based coeducational higher education institution in Mati City, Davao Oriental, Philippines. It was founded on December 13, 1989.
Davao Oriental State University (DOrSU) was established through Republic Act No. 11033, signed into law by President Rodrigo Roa Duterte at the Malacañang Palace on May 28, 2018. Its conversion is an end-product of House Bill 7007 authored by Congress Representative Joel Mayo Z. Almario and Senate Bill 1617 filed by Senator Joel E. Villanueva. President Emeritus Edito B. Sumile successfully paved the groundwork for the University conversion and was sustained by his successor, Dr. Roy G. Ponce, later named the first University President. Also instrumental to the success of the conversion process is the forward-looking initiative of Hon. Thelma Z. Almario and the dynamic leadership of the Commission on Higher Education (CHED) under Chairperson Julian Prospero E. De Vera III and Commissioner Aldrin A. Darilag, Presiding Chair of the DOrSU Board of Regents, as well as the Committee on Higher and Technical Education (CHTE) chaired by Hon. Mark O. Go.
