Phoebe Philo (Paris, 1973-) is an English fashion designer.

Phoebe Philo is a former fashion designer of the fashion house Chloe. Philo began working for Chloe in 1997 as Stella McCartney's design assistant. Philo succeeded McCartney as creative director of the iconic luxury label in 2001 after McCartney was offered the chance to start her own label with the Gucci Group. Philo resigned from her role at Chloe on January 5, 2006. Her reasons for leaving included a desire to spend more time with her family.

Philo graduated from Central Saint Martins College of Art and Design in 1996, a year after Stella McCartney. When McCartney landed the job at Chloe, she decided to bring Philo along as an assistant. Philo claims that she learned a lot about design from McCartney and many say that Philo added a "street sensibility" to McCartney's designs.Like McCartney, Philo is a vegetarian and will not work with fur, but whereas McCartney (a strict vegetarian) will not work with leather either, Philo will.

Philo has, at times, been credited with making Chloe cool again, as it had been in the 1960's and 1970's under the rule of fashion-zeitgeist, Karl Lagerfeld. Some of the It items produced by Chloe under Phoebe Philo include high-waisted jeans and babydoll dresses, wooden wedge shoes (something of a phenomenon at the time) and stack heeled buckled boots, horn, bat and fossil butterfly necklaces and of course, the Bracelet, Camera, Silverado, Paddington (arguably the most popular It Bag of all time), Betty and Edith handbags, which adorned the arm of every celebrity and celebrity-wannabe.
