Gap, commonly known as Gap Inc. or The Gap, is an American multinational clothing and accessories retailer. It was founded in 1969 by Donald G. Fisher and Doris F. Fisher and is currently headquartered in San Francisco, California. The company operates five primary divisions: the namesake banner, Banana Republic, Old Navy, Piperlime, and Athleta. Gap Inc. was surpassed by Spanish-based Inditex Group as the world's largest apparel retailer, though it remains the largest specialty retailer in the United States. As of September 2008, the company has approximately 135,000 employees and operates 3,076 stores worldwide, of which 2,551 are located in the U.S.

The Fisher family remains deeply involved in the company, collectively owning much of its stock. Donald Fisher served as Chairman of the Board until 2004, playing a role in the ouster of then-CEO Millard Drexler in 2002, and remained on the board until his death on September 27, 2009. Fisher's wife and their son, Robert J. Fisher, also serve on Gap's board of directors. Robert succeeded his father as chairman in 2004 and also served as CEO on an interim basis following the resignation of Paul Pressler in 2007, before being succeeded permanently by Glenn K. Murphy.
