The Palace of Earthly Tranquility (simplified Chinese: 坤宁宫; traditional Chinese: 坤寧宮; pinyin: Kūnníng Gōng; Manchu: ᡴᡠᠨ ᠨᡳᠩ ᡤᡠᠩ kun ning gung) is the northernmost of the three main halls of the Inner Court of the Forbidden City in Beijing, China.

In the Qing dynasty, large portions of the Palace were converted for Shamanist worship by the Manchu rulers.

Thus, the front part of the hall featured shrines, icons, prayer mats, and a large kitchen where sacrificial meat was prepared.

However, two rooms in the Palace of Earthly Harmony were retained for use on the Emperor's wedding night.
