Meaning & origin

Diem is a name of uncertain origin that has been in use in the United States since at least 1980, when it first appeared in Social Security data. Its peak popularity came in 2012, when it ranked 11,932th overall. Since 2016, its usage has been falling, and in the latest year it was given to approximately 1 in 229,610 newborns. The name may be a modern English respelling or a borrowing from Vietnamese, where Diệp means 'leaf'. Its simple, two-syllable sound and exotic feel may appeal to parents seeking a distinctive choice. While not widely used, Diem's sparse history leaves room for individual interpretation.

Diem is a name of uncertain origin. It may be a modern coinage derived from the Vietnamese name Diệp, meaning 'leaf', or a respelling of the Latin word diem meaning 'day'. In the United States, it has been in occasional use since the 1980s, possibly influenced by the Vietnamese diaspora. Its usage peaked in 2012 and has since declined.
