Meaning & origin

Libby has been in consistent use since at least 1881, when it first appeared in Social Security records. Its popularity reached a peak in 2010, but it has been on a gradual decline since 2009. In the most recent year (2025), it ranked 1144th, with approximately 1 in 7957 baby girls receiving the name. The name is most prevalent in New York, Arkansas, and South Carolina, reflecting its distribution across different regions of the United States. As a diminutive of Elizabeth, Libby retains a classic charm while feeling approachable and friendly, making it a familiar yet not overly common choice.

Libby originated as a pet form of Elizabeth, which comes from the Hebrew name Elisheva, meaning 'God is my oath' or 'God's abundance.' The nickname became an independent given name in its own right, particularly in English-speaking countries, and has been used since at least the 19th century.
