Tourism in Puerto Rico attracts millions of visitors each year, with more than 5.1 million passengers arriving at the Luis Muñoz Marín International Airport in 2022, the main point of arrival into the island of Puerto Rico. With a $8.9 billion revenue in 2022, tourism has been a very important source of revenue for Puerto Rico for a number of decades given its favorable warm climate, beach destinations and its diversity of natural wonders, cultural and historical sites, festivals, concerts and sporting events. As Puerto Rico is an unincorporated territory of the United States, U.S. citizens do not need a passport to enter Puerto Rico, and the ease of travel attracts many tourists from the mainland U.S. each year.

Puerto Rico, officially the Commonwealth of Puerto Rico, is a Caribbean island, Commonwealth, and unincorporated territory of the United States. It is located in the northeast Caribbean Sea, approximately 1,000 miles (1,600 km) southeast of Miami, Florida, between the Dominican Republic and the U.S. Virgin Islands, and includes the eponymous main island and several smaller islands, such as Mona, Culebra, and Vieques. With roughly 3.2 million residents, it is divided into 78 municipalities, of which the most populous is the capital municipality of San Juan. Spanish and English are the official languages of the executive branch of government, though Spanish predominates.
