Elephant & Castle Market, which is currently open 6 days a week, will also be held on Sundays with a special focus on food.
"The weekday market is one of the main attractions of Elephant & Castle Shopping Centre and has helped contribute to an amazing milestone of up to one million people now visiting the centre each month," says James Stockdale, development manager at St Modwen, the owner of the shopping centre.
"The Sunday market, with its focus on food, will bring a tasty and colourful new dimension to the local area and contribute to the centre's ongoing success. It's going to be a real winner."
Elephant & Castle Market has been operating since 1992 in the spaces outside the Elephant & Castle Shopping Centre, close to the entrance to the Northern line tube station.
Last year market operators Urban Space Management signed a new five-year lease with St Modwen, securing the future of the market till at least 2014.
From Sunday 11 April the food market will be open every Sunday between 10am and 4pm.
The food market will offer seasonal fruit and veg, fresh bread and a variety of international food-to-go including jerk chicken, Mexican treats, Hungarian goulash and Indian curry as well as French crepes and a British hog roast.
"Since establishing the market in 1992, we've enjoyed watching it grow and flourish along with the surrounding area," says Martyn Willls, project manager at USM.
"With the timing of the regeneration still uncertain, we hope that the Sunday market will be a great new shopping attraction for the local community."
