Kahansin () is a deity of Goguryeo. Along with Yeongseongsin (), Ilsin (), Susin (), and Kijasin (), It was one of the major deities in the 7th-century Goguryeo pantheon. According to the Book of Tang:
Since the term “Kahansin” uses the same Chinese characters as “Kehán” (可汗), the Chinese transliteration of the Mongolian and Turkic imperial title “Khagan,” some scholars view Kahansin as the deified form of the Khagan. In this case, it is believed that they worshipped the Kahansin in order to strengthen relations with the Göktürks and Khitans, who were nomadic tribes in the north bordering Goguryeo at the time. Other scholars suggest that the Kahansin refers to Dangun of Gojoseon or the founding deity of Goguryeo.
