Portobello Road Market draws thousands of tourists each year. The main market day for antiques is Saturday, the only day when all five sections are opened: second-hand goods, clothing and fashion, household essentials, fruit, vegetables and other food, and antiques. However, there are also clothing, antique, bric-a-brac, fruit and vegetable stalls throughout the week and are located further north than the antiques, near the Westway Flyover. Shops and cafes are opened daily.

The market began as many other London markets and mainly sold fresh-food in the 19th century; antiques and wares dealers arrived in the late 1940s and '50s, and gradually antiques have become the main attraction of this market, having a substantial number of them trading mainly on Saturday mornings. It is the largest antiques market in the UK.
