Chulalongkorn University in Thailand comprises nineteen constituent faculties, as well as six schools and colleges, which form the university's teaching units. Together, they offer 76 undergraduate and 375 postgraduate programmes, and (as of the 2018 academic year) host the university's 25,940 undergraduate and 11,424 postgraduate students.^[1] Each of the faculties is focused on a specific subject area. All undergraduate and most postgraduate students will apply for a programme of study under a specific faculty, and will belong with that faculty throughout the duration of their studies.

The university was established in 1917 with four original faculties: Medicine, Public Administration, Engineering, and Arts and Science. Of the four, only the faculties of Engineering and of Arts and Science remain with the university, while many others have been created or added. The university now has faculties dedicated to all major fields of study.

When the Civil Service College of King Chulalongkorn was re-established as Chulalongkorn University in 1917, three of its five constituent schools were reorganized into the university's four original faculties: the Faculty of Medicine, Faculty of Public Administration, and Faculty of Engineering. The Faculty of Arts and Science was newly established to cover non-specialized areas of knowledge.^[2]

Reorganization in the period following the abolition of absolute monarchy in 1932 resulted in the transfer of several faculties. The Faculty of Public Administration was merged with the Law School of the Ministry of Justice to become the Faculty of Law and Political Science in 1933, and was transferred to the newly established University of Political and Moral Sciences (now Thammasat University) in 1934. The Faculty of Medicine was transferred to the University of Medical Sciences in 1943; it is now known as the Faculty of Medicine Siriraj Hospital, Mahidol University.^[3] Conversely, the department of architecture at Poh-Chang School was transferred to Chulalongkorn University in 1932, and became the Faculty of Architecture in 1939.^[4] The Faculty of Arts and Science was split into the Faculty of Arts and Faculty of Science in 1943.^[3] Most of the university's faculties were founded between 1934 and 1958. New faculties, schools and colleges continue to be established, and the university now has nineteen constituent faculties, as well as six schools and colleges.

The faculties are tasked with education, research, student development, and academic services in their respective fields, while the colleges hold similar roles but are limited to postgraduate studies. They are administratively equivalent, as are schools, which function like faculties but on a smaller scale. Each is headed by a dean, who chairs its administrative committee and oversees its operations and management. Faculties are responsible for the programmes and courses they teach, as well as student affairs and personnel management (with the establishment of programmes and assignment of higher academic positions subject to approval by the University Council).^[5]
