The Si Satchanalai Historical Park (Thai: อุทยานประวัติศาสตร์ศรีสัชนาลัย) is a historical park in Si Satchanalai district, Sukhothai Province, northern Thailand. The park covers the ruins of Si Satchanalai and Chaliang. Si Satchanalai, which literally means "City of good people", was founded in 1250 as the second center of the Sukhothai Kingdom and as a residence of the crown prince in the 13th and 14th centuries.

The city was rectangular in shape. In the 16th century, a 5-metre high wall with an upstream moat was built to fend off the growing Burmese attacks. The location of the town was facilitated by two neighboring dominant hills. The park is maintained by the Fine Arts Department of Thailand with help from UNESCO, which has declared it a World Heritage Site together with the associated historic parks in Kamphaengphet and Sukhothai. Similar to Sukhothai Historical Park, Si Satchanalai Historical Park attracts thousands of visitors each year, who marvel at the ancient Buddha figures, palace buildings and ruined temples. The park is easily toured by bicycle or even on foot.

Prior to the 13th century, Tai migrated into upper Chao Phraya valley and established a town named Chaliang (Thai: เมืองเชลียง), which means "City of Water" on the bank of the Yom River. Chaliang gradually developed into an important trade center between China and Khmer Empire. The Chinese called the town "Chengliang". The town enjoyed a substantial autonomy under Khmer until 1180, during the reign of Pho Khun Sri Naw Namthom who was the local ruler of Sukhothai and Sri Satchanalai, Khmer general Khomsabad Khlonlampong started to take control directly and introduced prohibitive taxes. In 1239 Pho Khun Bangklanghao and Pho Khun Pha Mueang decided to rebel and declare independence from Angkor and captured Chaliang. Chaliang then became part of the Sukhothai Kingdom.
