Khon Kaen (Thai: ขอนแก่น, pronounced [kʰɔ̌ːn kɛ̀n]; Northeastern Thai: ขอนแก่น, pronounced [kʰɔ̌ːn kɛ́n]) is one of Thailand's 76 provinces (changwat). It is a triply-landlocked province in central northeastern Thailand. Neighboring provinces are (from north, clockwise) Nong Bua Lamphu, Udon Thani, Kalasin, Maha Sarakham, Buriram, Nakhon Ratchasima, Chaiyaphum, Phetchabun, and Loei.

A Sanskrit inscription of the Zhēnlà king Citrasena comes from the moated site of Wat Si Mueang Aem, and the oldest inscription from the province, of the eighth century, is in Old Mon. Khon Kaen University and the provincial hospitals make the city a medical and educational centre of Isan.

History

Several bronze and iron tools used as axes have been discovered in the province, along with a bronze ring attached to a skeleton. A copper axe from the province, of 4,600 to 4,800 years ago (2800 to 2600 BC), has been reported as the oldest in Southeast Asia.

A Sanskrit inscription of the Zhēnlà king Citrasena, K.1102, comes from the moated site of Wat Si Mueang Aem in Ban Dong Aem area, about forty kilometres north of Khon Kaen and 200 m from the Suea Ten canal.: 91, 97 : 76  Brick ruins, a stone Nandi and a shivalinga have been found inside the moat.: 91, 97  Chaowanee Lekkla places the site 500 km north-west of Sambor Prei Kuk by that canal.: 91, 97  It is the northernmost of nine inscriptions recording Citrasena-Mahendravarman's victories beyond the Dangraek range, which Sarah Talbot, on Coedès and Vickery, treats as cries of victory that do not imply permanent occupation.: 76 

During the Dvaravati period, Khon Kaen was influenced by the culture of the central region. The oldest inscription found in the province dates to the 8th century and is written in the Old Mon language. It has been read as evidence of Mon people in the area at that time.: 93  Talbot, on Jacques, reports a short undated inscription held in the National Museum in Khon Kaen that is entirely in Mon except for a Khmer phrase meaning lord of the lower surface, which designates kingship.: 79  The Dvaravati culture is believed to have played a significant role in the region, and the Nyah Kur people are thought to be descendants of the Dvaravati Mon people.: 75  During the 10th–11th centuries and onwards, the area came under Khmer influence, as evidenced by various inscriptions.: 166  The area fell into the control of Lan Xang before coming under Central Thai control.

Dvaravati sema stones from the province have also been studied and re-used. Piriya Krairiksh published a study in 1974 of sema in the Khon Kaen National Museum carved with scenes from the Mahānipāta jātakas.: 266  At Ban Bua Semaram in Chum Phae district a sema marks the boundary of the village, set beneath a modern road sign. Stephen Murphy gives it as an example of the stones being put to a use of the villagers' own.: 278 

Vimoltip Singtuen and colleagues examined the stone itself at two sites in the province in 2025. At the ancient town of Non Nong Khu in Ban Ruea subdistrict, Phu Wiang district, a broken sema 83 cm high lay inverted beside a laterite road at the northeastern edge of the moat. A sandstone pillar 140 cm high and smaller worked pieces were found nearby.: 4  Thin-section petrography and portable X-ray fluorescence classed all of them as sublitharenite of the Phu Kradung Formation, on which the town stands. An unfinished sema at Tham Phra Kho Khat, in Nong Phai subdistrict of Chum Phae district, is quartz arenite to sublitharenite matching the Phra Wihan Formation of the surrounding Phu Wiang range.: 2, 5  The authors conclude that each site drew on stone close at hand, but note that some samples carry two geochemical signatures and may mix material from more than one source.: 6, 8 

At Tham Phra Kho Khat a rock shelter holds a seated sandstone Buddha 64 cm high whose head has been rebuilt in cement and gilded. A stone marker, possibly a sema, was removed from the site, and three fragments were later recovered, one carved with the axis of a stupa.: 9  Surface survey at Non Nong Khu produced earthenware, high-fired Khmer and Lan Xang wares, Chinese porcelain, spindle whorls, stone rollers, tobacco pipes and iron-smelting slag.: 2  The surveyors divided the finds into a Dvaravati–Lopburi phase of about the 8th to 13th centuries and a Lan Xang phase of about the 16th to 19th.: 8  Satellite imagery and geographic information systems were used to identify further settlements, iron-smelting sites, salt-production areas and cart tracks in the same area. The survey also found that local landform words such as non, kok, don and kut often mark places with archaeological remains.: 2 

The first city of the area was established in 1783 when Rajakruluang settled there with 330 people. King Rama I made Rajakruluang the first governor of the area when establishing tighter connections with the Isan area. The main city was moved six times until in 1879 it reached its present-day location at Nuang Kaw. Khon Kaen was under the governance of Udon in the early period of Rattanakosin, c. 2450 BE. Khon Kaen was incorporated as a city in 1797. Mancha Khiri was among the towns detached from Suwannabhumi and made part of Khon Kaen province after 1797.

Symbols

The seal of the province shows the stupa (tower) of Phra That Kham Kaen, which is believed to contain relics of Buddha. A tree is depicted on each side. One is a banyan tree (Ficus benghalensis), the other a Golden Shower Tree (Cassia fistula). The Thai name of the golden shower means 'providing support and preventing a decline', and it is also the provincial flower. The provincial tree is the pink shower tree (Cassia bakeriana), the Thai name of which translates as 'wishing tree'. The provincial aquatic life is the edible carp Osteochilus melanopleura.

The mayor of Khon Kaen in 2005 chose Sinxay to be the new identity of Khon Kaen and had finials designed representing Sinxay and his two brothers, Siho and Sangthong. The story of Sang Sinxay is a work of Lao literature written by Pang Kham in 1649, during the Lan Xang period.
