Hup taem or hoop taem (Thai: ฮูปแต้ม, lit. 'picture painting') is an Isan folk art style of murals found on the ordination halls, or sim, at Buddhist temples. Some hup taem are influenced by traditional Thai and Lan Xang artistic conventions, but the Isan folk art style created by local artists called chang taem (ช่างแต้ม) features simple techniques with few elements. These hup taem murals are found mostly in Khon Kaen, Roi Et, and Maha Sarakham provinces in Northern Thailand.
