Guilaine is French in Origin.

Guilaine is a French feminine given name, an orthographic variant of Ghislaine. It traces back to the medieval Germanic element gīsil, meaning “pledge” or “hostage,” which in name lore broadened to “noble child” or “offspring of a noble line.” The feminine ending -aine mirrors the masculine Ghislain, yielding a sense often rendered as “pledge; noble lineage.”

Usage followed the spread of the cult of Saint Ghislain, a seventh‑century monk revered in Hainaut (now Belgium), which anchored the name in northern France and Wallonia. The feminine form gained wider visibility in the 19th–20th centuries, when French given names saw archaic revivals; Guilaine represents a modernized spelling within that trend. Today it remains uncommon but distinctly Francophone. Variants and cognates include Ghislaine (standard), Ghyslaine, Gislaine (Portuguese/Brazilian), and the masculine Ghislain; related names from the same root are Gisela and Giselle.
