Emperor Go-Momozono (後桃園天皇 Go-Momozono-tennō) was the 118th emperor of Japan, according to the traditional order of succession.

Go-Momozono's reign spanned the years from 1771 through his death in 1779.

This 18th-century sovereign was named after his father Emperor Momozono and go- (後), translates literally as "later"; and thus, he could be called the "Later Emperor Momozono". The Japanese word "go" has also been translated to mean the "second one"; and in some older sources, this emperor might be identified as "Momozono, the second," or as "Momozono II".
