Madeira Airport, informally Funchal Airport, formerly Santa Catarina Airport and officially Cristiano Ronaldo International Airport, is an international airport in the civil parish of Santa Cruz in the Portuguese archipelago and autonomous region of Madeira. The airport is located 13.2 km (8.2 mi) east-northeast of the regional capital, Funchal, after which it is sometimes informally named. It mostly hosts flights to European metropolitan destinations due to Madeira's importance as a leisure destination, and is pivotal in the movement of cargo in and out of the archipelago of Madeira. It is the fourth-busiest airport in Portugal. The airport is named after Madeiran native Cristiano Ronaldo, considered one of the greatest footballers of all time. During its renaming ceremony in 2017, the airport drew media notoriety for an infamous bust of Ronaldo unveiled at the ceremony, now replaced.

Funchal is the capital, largest city and the municipal seat of Portugal's Autonomous Region of Madeira, bordered by the Atlantic Ocean. The city has a population of 105,795, making it the sixth largest city in Portugal. Because of its high cultural and historical value, Funchal is one of Portugal's main tourist attractions; it is also popular as a destination for New Year's Eve, and it is the leading Portuguese port on cruise liner dockings.
