Meaning & origin
Brenin is a Welsh name meaning "king," directly taken from the noun. It first appeared in U.S. records in 1985 but has never been common. Its peak year of use was 2011, after which its popularity has been falling. In 2025, the name ranked 12,008, given to about 1 in 341,615 boys. Despite its regal meaning, Brenin remains an uncommon choice, largely used within Welsh or Celtic-inspired naming. The name has no top states of concentration, reflecting its widespread but very sparse usage across the country. Its trajectory has been slowly declining since around 2010, suggesting it appeals to a niche audience seeking a distinctive name with a strong meaning.
Brenin is the Welsh word for "king." It has been used as a given name in Wales and among Welsh-speaking communities, though it remains relatively rare. The name is a direct adoption of the noun, similar to other titles used as first names.
