Denver International Airport (IATA: DEN, ICAO: KDEN, FAA LID: DEN), often referred to by locals as DIA, is an international airport in the Western United States, primarily serving metropolitan Denver, Colorado, as well as the greater Front Range Urban Corridor. Runway 16R/34L, with a length of 16000 ft (4877 m), is the longest public use runway in North America and the fifth longest in the world. The airport is 25 miles (40 km) driving distance northeast of Downtown Denver, 19 miles (31 km) farther than the former Stapleton International Airport which DEN replaced; the airport is actually closer to the city of Aurora than central Denver, and many airport-related services, such as hotels, are located in Aurora. Opened on February 28, 1995, DEN serves 26 airlines (as of 2025) providing nonstop service to 230 destinations throughout the Americas, Europe, and Asia; it was the fourth airport in the United States to exceed 200 destinations. The airport has been the largest operating hub for Frontier Airlines and Southwest Airlines for several years and, as of 2024, DEN has eclipsed Chicago's O'Hare International Airport as the largest operating hub for United Airlines as well. The Colorado Department of Transportation's 2025 Economic Impact Study estimated that the airport contributes $47 billion annually to Colorado's economy and, with over 40,000 employees, the airport is the largest employer in the state of Colorado. The airport is located on the western edge of the Great Plains and within sight of the Front Range of the Rocky Mountains. In 2021 and 2022, DEN was the third busiest airport in the world as well as the third busiest airport in the United States by passenger traffic. In 2023, it was the sixth busiest airport in the world and remained the third busiest in the United States, having served around 77 million passengers, more than a 12% increase from the prior year.

In 2025, DEN set an all-time passenger record with 82,427,962 passengers served, up 0 % over the previous record set in 2024.
