Meaning & Origin
A surname from Old French, variant of Lacey
Laci is a girl's baby name, a variant spelling of Lacey or Lacy, from an Old French surname meaning 'from Lassy' — a Norman place name. Lacey entered the American given-name mainstream in the 1980s and 90s as a friendly, approachable choice.
The 'i' ending gives Laci a playful, modern look. It carries the same casual warmth as Caci, Kaci, and Traci — names that wear well from childhood through adulthood with effortless ease.
