Dougong (Chinese: 斗拱; pinyin: dǒugǒng; lit. 'cap [and] block') is a structural element of interlocking wooden brackets, important in traditional Chinese architecture for both its structural capacities and cultural implications.

The use of dougong first appeared in buildings of the late centuries BCE, with its earliest renditions emerging during the Western Zhou Dynasty, evolving over the centuries into a structural network which joined pillars and columns to the frame of the roof. Dougong were widely used by the ancient Chinese during the Spring and Autumn period (770–476 BCE) and developed into a complex set of interlocking parts by its peak in the Tang and Song periods. The pieces are fitted together by joinery alone without glue or fasteners, requiring precise carpentry.
