Chiang Mai University has four campuses, three of them in Chiang Mai and one in Lamphun, which together cover about . There are 18 housing complexes located on campus for students attending the university. Seventeen of them are on the main campus and one is on the Mae Hea campus
Suan Sak Campus (main campus) The main university campus, known as Suan Sak campus () or Cherng Doi (), lies about five kilometres west of the city centre. Set against
Doi Suthep, the campus occupies a site, bounded on three sides by main shopping streets and on the fourth by the
Chiang Mai Zoo. The campus includes the university's administrative centre; the science, engineering, humanities, social science, political science and public administration, law and graduate school, all of the campus resource facilities and services and major sports facilities. An attractive feature of this campus is the
Ang Kaew Reservoir. Constructed to supply water for the university, it is also a recreational area for campus residents and the local community. In the 1960s, the area was still forested. With conservation in mind, university buildings were constructed between the trees, with the result that the campus still retains much of its original setting.
Suan Dok campus Near the main campus, and closer to the city, opposite
Wat Suan Dok, the health sciences complex, the Suan Dok campus (), occupies a site which includes faculties of medicine, associated medical sciences, nursing, dentistry, pharmacy, and
Maharaj Nakorn Chiang Mai Hospital, known locally as Suan Dok, the largest teaching hospital in northern Thailand.
Mae Hia campus About 5 km south of the main campus, the
Mae Hia (or Mae Hea) campus () is home to the faculties of veterinary medicine and agro-industry. The Energy Research and Development Institute (ERDI), the university centre for renewable energy (mainly
biogas and
biomass), and
the energy efficiency improvement centre moved from the main campus to the Mae Hia campus in January 2009. This centre is a national "biogas centre of excellence", emphasising biogas activities, especially biogas on swine farms.
Si Bua Ban campus The university's latest acquisition is the Si Bua Ban campus () in
Amphoe Mueang Lamphun, Lamphun Province, about 55 kilometres south of Chiang Mai, on a site close to the Lamphun industrial centre. == Academics ==
