The Lega Basket A (officially: Lega Società di Pallacanestro Serie A,[1][2] English: Basket League) is the organizing body, as delegated by the Italian Basketball Federation, of the top division of Italian professional men's basketball league, the Serie A (English: Basket League A Series).

It is composed of the clubs that participate in the Lega Basket Serie A.

Discussions have been held as to the possibility of Basket League gaining more autonomy, similarly to that of the corresponding football organization, Lega Serie A.

The current president of Basket League is Fernando Marino.

On June 20, 2001, it changed to include just the first division Serie A clubs.
