The short answer
Lia is a feminine name with two documented sources on Behind the Name. As "Lia (1)", it is the Italian, Portuguese, Georgian and Greek form of Leah, the Hebrew name of Jacob's first wife in the Old Testament, probably meaning "weary, grieved". As "Lia (2)", it is simply a short form of any name ending in -lia, such as Julia or Rosalia, used in Italian, Dutch and German. Both are pronounced LEE-ə. Lia ranked #200 for girls in the United States in 2025.
Meaning and etymology
Behind the Name records Lia as two separate entries. The primary entry, Lia (1), is the "Italian, Portuguese, Georgian and Greek form of Leah"; looking up Leah gives the underlying Hebrew meaning "weary, grieved" (with an alternative link to Akkadian littu, "cow"), and identifies Leah as Jacob's first wife in Genesis. A separate entry, Lia (2), describes Lia as simply a "short form of Rosalia, Julia and other names ending in lia", used in Italian, Dutch and German.

What the name feels like
Lia works as a name in its own right, but its charm is partly its flexibility: it can stand alone, land as the natural short form of a longer -lia name, or serve as a cross-cultural spelling of Leah.
Style tags: short and vowel-forward, cross-cultural, biblical (as Leah), nickname-name
Editorial interpretation: This style framing is editorial opinion. The two distinct Behind the Name entries (form of Leah vs. short form of -lia names) are documented fact; the description of Lia's 'flexibility' as a style trait is subjective.
