The Lega Nazionale Professionisti B, commonly known as LNPB or Lega B, is the governing body that runs the second tier of professional football competitions in Italy, the Serie B. It was previously known as Lega Nazionale Professionisti Serie B or just Lega Serie B. It was founded on 7 July 2010, following a split between Serie A and Serie B clubs, which led to the dissolution of the Lega Calcio and creation of two new leagues, the Lega Serie A and Lega Serie B respectively.
