Irina Lazareanu (born 8 June 1982) is a Romanian-Canadian model. Romanian-born Lazareanu got her ‘big break’ through her acquaintance with model Kate Moss.

At age 17 Lazareanu attended an open call and signed with Giovanni modelling agency in Montreal with the hopes that it would help pay rent. From then on she did the usual rounds of London and Paris, occasionally appearing in Barcelona, Australia and Madrid fashion weeks. It wasn't until she was chosen by acquaintance Kate Moss to model for the December/January issue of Vogue: Paris, which she guest edited that Lazareanu received notice by fashionistas. Lazareanu has since become an increasingly popular fashion model, breaking the record for most runway work in one season.

She has modeled for many top designers, including Chanel, Balenciaga, Alexander McQueen, Anna Sui, Lanvin, Versace, and many more. She is affiliated with the modeling agencies Marilyn (New York and Paris), Why Not Models (Milan), Select Model Management (London), and Giovanni (Montreal). In March 2007, Lazareanu was chosen by Kate Moss as the model for her new Topshop clothing range

FRP would like to salute Irina Lazareanu as one of the top 50 models of the last decade.
