Meaning & origin

Leiby is an extremely rare American masculine given name, first recorded in U.S. birth data in 2000. In 2025, it ranked 3,949th, with an estimated 1-in-63,262 frequency, marking its peak year to date. The name has been gradually rising in usage since 2006, though it remains uncommon, with no concentration in any top states. As a modern adaptation of the Yiddish name Leib, it reflects a broader trend of reviving Ashkenazi Jewish names with affectionate suffixes. Its recent emergence and steady upward trajectory suggest a niche but growing appeal, particularly within communities seeking distinctive traditional names.

Leiby is a modern American variant of the Yiddish name Leib, which itself is a diminutive of the Hebrew name Yehudah (Juda). In Ashkenazi Jewish tradition, Leib (meaning 'lion' in Yiddish) was often used as a secular given name. The -y suffix is a common American English diminutive. The name gained rare usage in the United States beginning in the early 2000s.
