Emperor Kameyama was an emperor of the Kamakura period, reigning from 1259 to 1274.

As Retired Emperor, in 1291, Kameyama established the Buddhist temple Nanzen-ji on the grounds of one of his Kyoto villas.

His villa in the Arashiyama area of Kyoto was transformed in the 14th century into the Buddhist temple Tenryû-ji. He is buried there alongside Emperor Go-Saga (r. 1242-1246).

Kameyama was the common ancestor of the Daikakuji line of imperial succession, which alternated for a time with the Jimyôin line descended from his elder brother Emperor Go-Fukakusa. The division later developed into the Northern and Southern Courts of the Nanbokuchô Period, which competed in claims to the throne.
