, posthumously honored as , was the 110th emperor of Japan, according to the traditional order of succession.
Go-Kà Âmyà Â's reign spanned the years from 1643 through 1654.
This 17th-century sovereign was named after the 14th-century Nanboku-chà  Emperor Kà Âmyà  and go- (å¾Â), translates as later, and thus, he could be called the "Later Emperor Kà Âmyà Â". The Japanese word go has also been translated to mean the second one, and in some older sources, this emperor may be identified as "Kà Âmyà Â, the second", or as Kà Âmyà  II".
Before Go-Kà Âmyà Â's accession to the Chrysanthemum Throne, his personal name (his imina) was ; and his pre-accession title was .
He was the fourth son of Emperor Go-Mizunoo. His mother was Fujiwara no Mitsuko, the daughter of the Minister of the Left (Sadaijin); but he was raised as if he were the son of Tà Âfuku-mon'in. His predecessor, Empress Meishà Â, was his elder paternal half-sister.

Also enshrined are Go-Kà Âmyà Â's immediate predecessors, Emperor Go-Mizunoo and Empress Meishà Â.
