FedEx Corporation, originally known as Federal Express Corporation, is an American multinational conglomerate holding company specializing in transportation, e-commerce, and business services. The company is headquartered in Memphis, Tennessee. The name "FedEx" is a syllabic abbreviation of its original air division, Federal Express, which operated under this name from 1973 until 2000.

FedEx is best known for its air delivery service, FedEx Express, which pioneered overnight delivery as its flagship service. Over the years, the company has expanded its operations to include FedEx Ground, FedEx Office (formerly Kinko's), FedEx Supply Chain, FedEx Freight, and several other services through a network of subsidiaries. These expansions have often been strategic moves to compete with its primary rival, UPS. Additionally, FedEx supports the United States Postal Service (USPS) by transporting packages through its Air Cargo Network contract.

The company’s air shipping operations are centralized at its primary hub at Memphis International Airport, making it a critical hub for global logistics.
