Caroline Reboux (circa 1840–1927) was a Parisian milliner and French fashion designer. She opened her first boutique at 9 Avenue Matignon in Paris in 1865, which she continued to operate throughout her life. Reboux opened other shops in Paris and London starting in 1870. She trained other milliners who became famous in their own right, including American milliner Lilly Daché and French milliner Rose Valois. Reboux's most famous shop was located at 23 Rue de la Paix in Paris, which carried on operating after her death for almost three decades.
