Matthew Williamson is a fashion designer based in the United Kingdom. His collections are shown twice a year during New York Fashion Week, and they often have an Indian influence, perhaps related to the time Williamson spent working in India for the clothing store Monsoon.

He counts celebrities such as Sienna Miller and Jade Jagger amongst his friends, but has often been criticised by others in the fashion industry for using them to promote his designs.

In 1997 Matthew showed his debut collection at London fashion week.The collection was named 'Electric Angels'.
