Circle K Stores, Inc. is an international chain of convenience stores, owned by the Canadian multinational Alimentation Couche-Tard. Founded in 1951 in El Paso, Texas, the company filed for bankruptcy protection in 1990 and went through several owners, before being acquired by Alimentation Couche-Tard in 2003. As of February 2020, Circle K has 9,799 stores in North America (primarily in the United States and Canada), 2,697 stores in Europe, and an additional 2,380 stores operating under franchise agreements worldwide.

In 2015, Circle K unveiled a new logo and brand identity, and Couche-Tard announced that it would deploy the brand globally, including English-speaking Canada (rebranding from the Mac's brand), Europe (rebranding from the Statoil brand), and the United States (rebranding from the Kangaroo Express brand and updating the existing Circle K brand)
