Tosŏn Kuksa (Korean도선 국사; Hanja道詵 國師; 826-898), also known as Yogong Sŏnsa, Yŏn'gi Tosŏn, was a Korean Buddhist monk who lived during the decline of the Silla Dynasty, just prior to the foundation of the Goryeo Dynasty. At least 70 temples, monasteries and hermitages are claimed to have been founded either under Tosŏn's supervision and direction, or by orders of Taejo of Goryeo following Tosŏn's recommendations.

Tosŏn Kuksa is one of the Silla Dynasty's most well-known and oft-cited figures, remaining extremely influential throughout the remainder of Korean history up to the present.
