The name is found in German-speaking regions and among Ashkenazi Jewish communities, with various spellings or variants such as Leib in some languages.

In science and scholarship, the surname is associated with Elliott H. Lieb, an American mathematical physicist known for foundational contributions to quantum many-body theory. Notable results linked to his work include the Lieb-Liniger model of interacting bosons in one dimension, the Lieb theorem concerning certain electronic systems, and Lieb-Robinson bounds describing a finite speed of information propagation in quantum spin systems. These developments have influenced multiple areas of mathematical physics and have spawned further research and named results.

Culturally, Lieb may appear in historical German-language records as a descriptor or nickname meaning “beloved” or “dear.” The name is also encountered in genealogical contexts among families with Germanic or Ashkenazi Jewish ancestry. Variants and related surnames, such as Leib, reflect historical transliteration differences across regions and languages.
