Sung is a unisex given name of Korean origin, meaning 'double happiness' or 'beautiful jade'. It is composed of two Chinese characters, 'Song' (宋) and 'Ung' (永), where Song means 'to follow' or 'ascend', and Ung signifies 'eternal' or 'permanent'. Sung is traditionally a Korean male name but has also been used for females in recent years. It gained popularity internationally following the success of South Korean pop culture, particularly K-pop groups like BTS.
The name Sung experienced a surge in popularity between the late 1970s and early 1990s, with peaks of over 15 births per year from 1983 to 1992. However, it has since declined, with fewer than 10 births recorded annually since 2001. Overall, there were 444 babies named Sung between 1946 and 2006.
