Yuantong Temple (simplified Chinese: 圆通寺; traditional Chinese: 圓通寺; pinyin: Yuántōng Sì) is the most famous Buddhist temple in Kunming, Yunnan province, China. It is located in a protected natural depression and in recent years it has been expanded, with money from Thailand. In the 1950s, it hosted a grand ceremony to greet and send on the sacred teeth of the Buddha and so became important in Southeast Asia.

It was first built in the late 8th and early 9th century, the time of the Nanzhao Kingdom in the Tang Dynasty. After two major restorations and expansion in the Chenghua period (1465-1487) of the Ming Dynasty and the 24th year of Emperor Kangxi's rule (1686) of the Qing Dynasty, the temple took on its present design, with covered corridors, bridges and grand halls.

This old temple is noted for its unusual structure which is high at the front and low at the back, From the front archway named "Yuantong Shengjing" (Wonderland), one can behold the entire garden. To the north is the splendid Yuantong main hall. At both sides of the hall are covered corridors running beside clear pools. This structure of a Buddhist hall surrounded by water is unique in China. The main hall maintains the style of the Yuan Dynasty architecture. Circling the two central pillars inside the hall are two giant dragons carved during the Ming Dynasty. The blue and yellow dragons face each other, as if they are ready to fight.
