Meaning & origin

Elsi is a rare and modern name that first appeared in U.S. records in 1986. It reached its peak popularity in 2022, but has since been falling in usage. In 2025, it ranked 6,546th, with only about 1 in 94,545 baby girls receiving the name. The name is most frequently given in Texas. Elsi is a short, sweet name that feels like a fresh alternative to the more common Elsie or Elsa, while still carrying the weight of Elizabeth's ancient heritage.

Elsi is most likely a modern English diminutive or variant of Elsa or Elsie, which are themselves short forms of Elizabeth. Elizabeth derives from the Hebrew name Elisheva, meaning 'God is my oath.' Elsi emerged as an independent given name in the late 20th century, first recorded in 1986. Its use is relatively rare, with a peak in 2022.
