Kiét is a name of Vietnamese origin, meaning "intelligent" or "clever". It is derived from the Vietnamese word "kiệt", which has a similar meaning to the English word "talented". The name Kiét is believed to have been popularized during the Nguyen Dynasty (1802-1945), when many Vietnamese families chose names for their children that reflected desirable qualities such as intelligence, talent, and wisdom. Today, Kiét remains a popular name among Vietnamese families, both in Vietnam and among the Vietnamese diaspora around the world. Despite its popularity, however, Kiét is not a well-known name outside of Vietnamese communities, making it a unique and distinctive choice for parents looking for an uncommon yet meaningful name for their child.
The name Kiet had its peak popularity between 1986 and 1990, with over 10 births each year during this period. After the late 1990s, there was a significant decline in the number of babies named Kiet, with fewer than 10 births per year from 2003 onwards. The total number of births with the name Kiet between 1980 and 2019 is 342.
