Tampa International Airport (IATA: TPA, ICAO: KTPA, FAA LID: TPA) (known as Drew Field Municipal Airport until 1952) is an international airport six miles (9.7 km) west of Downtown Tampa, in Hillsborough County, Florida, United States. The airport is publicly owned by Hillsborough County Aviation Authority (HCAA). The airport serves 100 non-stop destinations throughout North America, Central America, the Caribbean and Europe across multiple carriers.

Tampa Bay is the birthplace of commercial airline service, when pioneer aviator Tony Jannus flew the inaugural flight of the St. Petersburg-Tampa Airboat Line on January 1, 1914, from St. Petersburg, to Tampa using a Benoist Flying Boat—the first scheduled commercial airline flight in the world using a heavier-than-air airplane.

In 1928, the city completed the 160-acre (65 ha) Drew Field six miles (9.7 km) west of Downtown Tampa. It was named for local developer John H. Drew, who formerly owned the land on which the airport stood. The more popular Peter O. Knight Airport was opened on Davis Islands near Downtown Tampa in 1935, where both Eastern and National Airlines operated until 1946.

The United States Army Air Corps began negotiating for the use of Drew Field in 1939 during the buildup of military forces prior to World War II. In 1940, the City of Tampa leased Drew Field to the U.S. Government for 25 years, or until the end of the "national emergency." During the war, the United States Army Air Forces expanded and modernized the airport. The airfield was used by the Third Air Force and renamed it Drew Army Airfield. The Third Air Force used it as a training center by 120,000 combat air crews, primarily in bomber aircraft for the European and Pacific theaters, and also flew locally based antisubmarine patrols from the airfield until that mission was fully taken over by Naval Aviation assets of the U.S. Navy and U.S. Coast Guard. There was one mishap in 1943 that killed five fliers. Despite this, Drew Field set a safety record for the Third Air Force in 1945 after 100,000 flying hours had been completed over a period of 10 months without a fatal incident. The aircraft operated included the Boeing B-17 Flying Fortress, Douglas C-47 Skytrain, North American AT-6, North American B-25 Mitchell, and others.

After World War II, the Army Air Forces vacated the facility and Drew Field was returned to the City of Tampa. The Peter O. Knight Airport and Drew Field reversed roles as the main Tampa airport because Drew Field was greatly expanded by the United States Army Air Forces during the war years. Airlines (Eastern Air Lines and National Airlines) moved to Drew Field from Peter O. Knight Airport on Davis Island, which was too small to handle the Douglas DC-4, DC-6 and Lockheed Constellation prop-liners then coming on line in the mid-1940s. During this period, the airlines were housed in the former Drew AAF Base Operations building.

Trans Canada Airlines international flights began in 1950 and Drew Field was renamed Tampa International Airport. The airport's second terminal opened in 1952 near the intersection of Columbus Drive and West Shore Blvd. The April 1957 Official Airline Guide shows 30 departures a day on Eastern Air Lines: nonstops to Chicago-Midway, Detroit (Willow Run), Cleveland, New York Idlewild (now JFK), Boston, seven nonstops to Atlanta and 18 within Florida. National Airlines had 26 departures, including seven nonstops beyond Florida to Houston Hobby, Havana, Washington National, New York/Idlewild and three to New Orleans. Trans-Eastern had 12 departures and Mackey had two DC-3s, none nonstop beyond Florida. Trans-Canada had thirteen nonstops a week to Toronto or Montreal.

The 1952 terminal, built for three airlines, was swamped after the Civil Aeronautics Board granted Capital, Delta, Northeast, Northwest and Trans World Airlines authority to fly from Tampa in the late 1950s. An annex was built east of the terminal for the new carriers. Turbine-powered flights began in 1959 on Eastern Air Lines' L-188 Electra; in 1960 National, Eastern and Delta Air Lines began jet flights with the Douglas DC-8 (Delta was first, with a Chicago nonstop in May or June). National DC-8 nonstops to Los Angeles and weekly Pan American jets to Mexico City (MIA-TPA-MID-MEX) started in 1961. The 1952 terminal was congested as larger jets replaced piston airliners and it was again expanded.

During the early 1960s, the aviation authority began planning a replacement terminal in an undeveloped site at the airport. Airport leaders chose the Landside/Airside design in 1965 after a study. Construction on the new terminal designed by Reynolds, Smith & Hills began in 1968 between the airport's parallel jet-capable runways. Days before its opening, the terminal was dedicated by Florida Governor Reubin Askew and 60,000 people toured the new facility during a two-day open house. The terminal opened for passenger traffic on April 15, 1971 with four airside satellites (Airsides B, C, D, and E). National Airlines Flight 36 from Los Angeles was the first to arrive at the terminal; after touching down at 05:26 A.M., the jet taxied to Airside E.

The graphics and signage system designed by Jane Davis Doggett used red for one group of airlines and blue for another. The red/blue color scheme began on the highway outside the airport and helped guide drivers to the proper dropoff areas for each airline, then continued to guide passengers through the airport itself and ultimately to their gate. The Tampa Airport was the first airport to use this sort of color-coded wayfinding signage system which was safer for drivers and required many fewer signs than highway engineers had originally budgeted for.

The logo, used since the new airport opened in 1971, represents the blue waters of Tampa Bay with a jetliner flying into the downtown Tampa sunset. It is known as the "Spirit of Flight". The jetliner was modeled after those once used for supersonic transport—at the time the logo was created in the 1970s, it was during an era when it was thought that supersonic aircraft would replace conventional jets as a mode of air travel.

In its early years, the 1971 terminal would also see large amounts of tourists heading to Walt Disney World, which also opened in 1971. This was due to the fact that Orlando International Airport (known then as Orlando Jetport at McCoy) was much smaller at the time with a more limited capacity. Shawnee Airlines offered connecting flights from Tampa to the now-defunct Walt Disney World Airport in the 1970s. Orlando International opened its current terminal in 1981 using the same well-received landside/airside layout as Tampa International Airport.

On July 15, 1972, the 207-foot-tall (63 m) air traffic control tower opened, the tallest in the United States at the time. The Host/Marriott Airport Hotel and its revolving rooftop restaurant opened in December 1973, with triple-paned windows and sound-proof guest rooms.

Northwest Airlines and National Airlines brought the jumbo jet to the airport late in 1971 with the introduction of the Boeing 747 and McDonnell Douglas DC-10. This was followed by the L-1011 Lockheed Tristar a year later by Eastern Air Lines. National Airlines began trans Atlantic DC-10 service to Amsterdam and Paris in 1977.

During the following decades, the airport was expanded to handle more traffic and additional airlines. In 1987, the terminal received its first major expansion with the opening of Airside F. Airside B closed permanently in 1991 following the demise of Eastern Air Lines. Airside A was subsequently built and opened in 1995. In 1996, Airsides C and D were temporarily closed and remodeled, and the interiors of both satellites were refurbished. During this time, all the airlines from both facilities were housed in Airside E. Upon completion of the renovations, the airlines returned to their original locations, and Airside E was permanently closed. Airside E sat dormant for a few years before eventually being demolished, with the current Airside E opening in 2002. The Landside Terminal was also remodeled multiple times during the 1980s and 1990s. Airside C and the abandoned Airside B were demolished in the mid-2000s, with the current Airside C opening in 2005. Airside D, the last original airside, was then closed permanently and was demolished in 2007.

Both Delta Air Lines and US Airways opened maintenance bases at the airport. Both bases closed during the air travel downturn following the attacks of September 11, 2001. Alabama-based Pemco World Air Services now occupies the former US Airways hangar performing MRO (maintenance, repair, overhaul) services for the Spirit Airlines and JetBlue A320 fleet. On April 1, 2010 a press release announced that a lease agreement was reached to allow Pemco to lease the second hangar formerly used by Delta Air Lines, where they perform Boeing 737 cargo conversions and modifications.

Phase I of the economy parking garage was completed in November 2005. Phase II of the economy garage opened ahead of schedule in November 2005, bringing a total of 5,600 parking spaces.

On March 7, 2011, federal officials gave TPA the green light to begin charter flights to Cuba as an official entry/exit point.

In 2007 and 2008, Zagat Survey ranked TPA the Best Overall U.S. Airport, while placing it second-best overall in 2009 and 2010. In 2008 Condé Nast Traveler recognized TPA as the second-best airport in the world, just two tenths of a point behind the first-place winner. JD Power and Associates have also given TPA Airport consistently high customer-satisfaction ratings over the years. In November 2011, CNN ranked TPA sixth among ten of the world's most loved airports, being the only one on the list from the US. In 2016, it was named one of the Top 3 airports in the country by Condé Nast. In 2020 Airports Council International named TPA the best airport in North America for its size. In 2024, Travel+Leisure ranked TPA the eighth best domestic airport in the US. Criteria for the rankings were based on access, check-in, restaurants,shopping, and design, and rated from excellent to poor. Readers of the magazine were involved in the survey. Palm Beach International Airport, another Florida airport, made the list (#3) as well.

In August 2022, a 21-foot flamingo sculpture named HOME nicknamed "Phoebe", was installed and opened in Tampa International Airport's main terminal. The design from American artist Matthew Mazzotta was chosen out of 734 art proposals submitted from around the world.

In February 2024, Joe Lopano, the CEO credited with leading Tampa's improvement as a hub, announced plans to retire. At the same time, the airport's board announced it would be undergoing an internal search for a replacement.
