The American Hotel & Lodging Association (AH&LA) was formed in 1910 as a federation of state lodging associations throughout the United States with some 13,000 property members worldwide, representing more than 1.7 million guest rooms. AH&LA was formally known as the America Hotel and Motel Association.

AH&LA provides its members with assistance in operations, education, and communications, and lobbies on Capitol Hill to provide a business climate in which the industry can continue to prosper. Individual state associations provide representation at the state level and offer many additional cost-saving benefits. AH&LA is associated with the American Hotel & Lodging Educational Foundation (AH&LEF) and the American Hotel & Lodging Educational Institute AH&LEI.
