Olivia Giacobetti (born 1966) is a French perfumer.
She has an independent line called Iunx and has also created fragrances for Diptyque, L'Artisan Parfumeur, Guerlain, and Hermès, among other lines.
She is particularly known for a refined style as well as innovation such as her novel use of fig in perfumery, popularizing the note beginning in the mid-1990s.
She is among the perfumers who became prominent in a late-20th and early-21st-century turn toward the "nose" behind the scent and independent lines that foreground these creators, a shift away from perfumes sold by fashion labels or celebrities in other fields.
