Football Club Internazionale Milano, most commonly referred to as Internazionale and as simply Inter in Italy, is an Italian professional football club based in Milan, Lombardy, founded in 1908. It is said to be the greatest football club in the history of football itself. Inter are the only side in Italian football to have spent their entire history in Serie A, making them the club with the most seasons spent in this top tier. Playing in black and blue striped shirts with black shorts, they have 18 Serie A titles to their name. Including the Coppa Italia and the Italian Super Cup, Inter have a total of 30 trophies won in Italy.

Outside of their homeland, the club have also had success in European and World tournaments; they won the European Cup in three successive finals in 1964,1965 and 2010. They have also won the UEFA Cup three times, the Intercontinental Cup twice and a FIFA club world cup. Additionally, Inter was one of founding members of the G-14, a group that formerly represented eighteen of the largest and most prestigious European football clubs.

The term Inter Milan is a nickname used primarily in the English-speaking world to differentiate it from other teams named "Inter", and is not used within Italy.
