Meaning & origin

Lillah is a rare and delicate-sounding name that first appeared in the United States in 1922. It reached its peak popularity in 2011, though it remains uncommon, with a rank of 10,107 in 2025 and an incidence of about 1 in 178,585 births. The name's trajectory has been falling since 2018, reflecting a broader trend away from softer, vintage-style names in recent years. While its origins are unclear, Lillah is often considered a variant of Lila or Lilla, giving it a lyrical quality that fits well with other short, vowel-ending names.

Lillah is a relatively modern name that first appeared in the United States in the early 20th century. It is likely a variant of Lila, which may derive from the Arabic word for 'night' or the Sanskrit word for 'play,' or from Lilla, a diminutive of Lilian. The name may also be a feminine form of Lil, short for William. Its usage has been rare but persistent, with a modest peak in the 2010s.
