Allama Iqbal International Airport (Punjabi / Urdu: علامہ اقبال بین الاقوامی ہوائی اڈا, IATA: LHE, ICAO: OPLA) is the third largest civilian airport by traffic in Pakistan, after Jinnah International Airport in Karachi and Islamabad International Airport. It serves Lahore, the capital of Punjab province, and the second-largest city of Pakistan. It also serves a large number of travellers from the other nearby regions of Punjab province.

Originally known as Lahore International Airport, it was renamed after the Islamic philosopher and poet Allama Muhammad Iqbal, one of the pioneers that led to the creation of Pakistan. The airport has three terminals: the Allama Iqbal terminal, the Hajj terminal and a cargo terminal. The airport is about 15 km from the city centre.

At the time of the Independence of Pakistan, Walton Airport was the main airport serving the city of Lahore. When Pakistan International Airlines (PIA) acquired its first jet aircraft, the Boeing 720, Walton Airport was unequipped to handle such an aircraft. The Government of Pakistan decided to build a brand new airport on the site of a 3 runway airbase, which opened in 1962. The airport had a specifically built runway and apron to handle aircraft up to the Boeing 747. This enabled Lahore to become accessible by international flights. PIA initiated direct flights to both Dubai, and London via Karachi.

Over the course of the next 25 years, the demand for air travel rose. The government had to build a bigger terminal to meet the growing needs of the region. In March 2003, a new terminal was inaugurated by President General Pervez Musharraf, originally commissioned by then ex-Prime Minister Nawaz Sharif. The airport was named Allama Iqbal International Airport and became the second largest airport in Pakistan after the Jinnah International Airport in Karachi. All flights were switched to the new airport and the old airport was passed onto the military. However, the government later reclaimed the airport from the military and developed it into a Hajj terminal.

The Pakistan Civil Aviation Authority awarded the main contract to Airsys ATM, leader of a consortium with J&P Overseas Ltd, an international building and civil engineering contractor. Airsys ATM is a joint project from Thomson-CSF Airsys and Siemens, dedicated to air traffic management systems and airport development. The Airports Group in the UK was also awarded a $70 million contract for airport systems construction. The project was implemented by a consortium of Joannou & Paraskevaides (J&P), responsible for civil and building works, and the Airports Group, responsible for the implementation of the system. Airsys ATM and Thales ATM were responsible for the fabrication and installation of the air bridges at the new terminal.

In March 2006, PIA inaugurated nonstop service between Lahore and Toronto using Boeing 777s. In 2008, the national flag carrier of the UAE, Etihad Airways, opened a dedicated aircraft line maintenance facility at the airport. The facility is used for day-to-day technical line maintenance on Etihad aircraft, including hydraulic structural and instrument checks.

In October 2020, British Airways resumed its direct flight operations to and from Lahore after 44 years. However, flights were prosponed 3 years later.

The Pakistan Civil Aviation Authority (PCAA) has planned to expand the terminal building, increasing the number of gates from 7 to 22, along with a corresponding rise in remote bays. This expansion will boost the annual passenger capacity of Lahore Airport from 6 million to 20 million, which will be sufficient to accommodate passenger demand for the next 15 to 20 years.
