The National Basketball League (Petronas-MoltenNational Basketball League for sponsorship reason), often abbreviated to the NBL, is the pre-eminent men's basketball league in Malaysia, organised by the Malaysia Basketball Association (MABA). The competition started as Malaysian Basketball League (MBL) in 1981. In 2002, MABA appointed Mr. Tan Kee Hian (Chinese: 陳其賢) to handle the competition and changed the league's name to National Basketball League (NBL).
NBL commissioner Tan Kee Hian announced on 24 July 2011, after the grand final of 2011 NBL, that they would take a break from the privately owned national league “after 10 years of struggling to keep the league afloat due to the lack of sponsors and teams”. However, the Malaysia Basketball Association (MABA) have promised to step in next year to keep the tournament alive.
