Mary Katrantzou (born January 1983) is a Greek fashion designer who lives and works in London.

Mary Katrantzou was born in Athens, Greece to an interior designer mother and a father who trained in textile engineering.^{[citation needed]}

In February 2008, Katrantzou opened the Saint Martins MA Fashion show at London Fashion Week. Her collection was nominated for the Harrods and the L‘Oreal Professional Award. Katrantzou's graduating show in 2008 mapped out her signature style. It was themed around trompe l'oeil prints of oversized jewellery featured on jersey-bonded dresses.^{[citation needed]} These pieces created the illusion of wearing giant neckpieces that would be too heavy in reality.
