Yen is a unisex given name of unknown origin, though it is sometimes associated with Chinese and Vietnamese cultures. In Chinese, 'Yen' (淵) means 'abyss' or 'depth', while in Vietnamese, it is often transcribed from Chinese characters to mean 'source'. The name Yen has gained popularity worldwide due to its unique sound and spelling, making it a distinctive choice for parents seeking an uncommon yet appealing name for their child.
The name Yen experienced varied popularity over time, with peaks in the late 1980s and early 1990s, but has since declined to a consistent low number of births annually.
