The Malaysia National Basketball League (Petronas-Molten Malaysia National Basketball League for sponsorship reason), often abbreviated to the MNBL, was 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 (simplified Chinese: 陈其贤; traditional Chinese: 陳其賢; pinyin: chén qí xián) to handle the competition and changed the league's name to Malaysia National Basketball League (MNBL).
MNBL commissioner Tan Kee Hian announced on 24 July 2011, after the grand final of 2011 MNBL, 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".[1]
In 2017, a new national league named the Malaysia Pro League (MPL) was established as a replacement for the Malaysia National Basketball League.[2]
