Maud Frizon de Marco (born Danielle Maud Frizon 1941, Paris, France) is a fashion designer specializing in women's shoes. She began her career in the 1960s as a model for Parisian Haute Couture Houses of Nina Ricci, Jean Patou, and André Courrèges. At the time models had to provide their own shoes to match the clothes designers assigned them for their runway shows and photo shoots. Frizon disliked the available shoes from other designers, and in 1969 elected to create her own and opened her first boutique in the Saint-Germain-des-Prés district of Paris.
That first shoe collection, with each pair hand-cut and finished, was praised by critics as sexy and unpredictable. Frizon was an immediate success. Building on the traditions of Beth Levine and foreshadowing the later designs of Manolo Blahnik, Frizon shoes were showy and extravagant, and her name joined the ranks of the haute couture boutiques. At the height of her success in the 1980s her reputation was similar to that of Blahnik today.
Frizon often used expensive and everyday materials together in unusual combinations: lizard and snake, suede and satin, canvas and crocodile. Brigitte Bardot was a regular at the boutique, famous for her love of Frizon's high-heeled Russian boots.
In Shoes – Fashion and Fantasy Colin McDowell wrote "If shoes can be said to have a personality, none have more so than the products of Maud Frizon's imagination. [They are] original and innovative shoes that [are] to footwear what Dom Perignon is to champagne". 
She is married to Luigi De Marco with whom she founded and operated her company.
In 1999 Frizon and De Marco sold the company and its brands to Helene Wajnblum-Liu and her husband, who added knits and leather clothing to the line as well as expanding the chain of Frizon boutiques. The firm remains headquartered in Paris, with boutiques in Paris, Brussels and Hong Kong.
