The Lega Basket Serie A (LBA) is a professional men's club basketball league that has been organised in Italy since 1920. Serie A is organised by Lega Basket, which is regulated by the Italian Basketball Federation (FIP). It is the highest-tier level of the Italian league system. The LBA plays under FIBA rules and currently consists of 16 teams, with the lowest-placed team relegated to the Serie A2 and replaced by the winner of the play-offs of that tier.
A total of 99 teams have competed in the LBA since its inception. Seventeen teams have been crowned champions, with Olimpia Milano having won the title a record 31 times, and Virtus Bologna 16 times. According to FIBA Europe's and Euroleague Basketball's national league coefficients, the LBA was the historically top ranked national domestic league in Europe, for the period 1958 to 2007. Today, the LBA is considered to be one of the top European national basketball leagues. Its clubs have won the most EuroLeague championships (13), the most FIBA Saporta Cups (15), and the most FIBA Korać Cups (10).
