The Willy Street Cooperative (locally known as the Willy Street Co-op) is a food cooperative located in Madison, Wisconsin that specializes in natural, organic and locally produced foods.

[1] The co-op is an economically and environmentally sustainable, cooperatively owned grocery business that serves the needs of its owners and employees.

WSGC supports local and organic suppliers throughout south-central Wisconsin.

[6] After years of planning and selecting two sites that didn't work out, the cooperative opened a second store, dubbed "Willy West," at 6825 University Avenue in Middleton in November 2010.

[9] Scenes from the comedy series Chad Vader: Day Shift Manager were filmed on location at the Willy Street Co-op, which serves as "Empire Market," the primary location for the series.
