The Malaysia A1 Semi-Pro League (Malay: Liga A1 Semi-Pro Malaysia, previously known as the Malaysia M3 League and the MBSB Bank Championship due to sponsorship reasons) is the second level football league of the Malaysian football league system. It was created as the Malaysian Football League's reform of the domestic structure and replacement of the Malaysia FAM League.
In 2018, the Malaysia M3 League was supposed to form the fourth division of the Malaysian football. However, the Football Association of Malaysia announced it as a replacement for the Malaysia FAM League to form the third division. After rebranding of the Football Malaysia Limited Liability Partnership (FMLLP) to the Malaysian Football League (MFL), the company announced a reform of the lower league competitions. In 2019, a new subsidiary known as the Amateur Football League (AFL), was formed. The AFL officially confirmed the formation of the Malaysia M3 League and the Malaysia M4 League as the third and fourth divisions.
A total of 14 clubs were confirmed to compete in the inaugural season of the newly reformed third division, with the Malaysia M3 League replacing the former Malaysia FAM League. Qualified champions from the 5 FA state leagues and 9 social leagues in 2018 were promoted to the inaugural 2019 Malaysia M3 League season. For the 2020 season, the Malaysia M3 League was divided into two groups of 10 clubs. At the end of the season, the top club from each group was promoted to the Malaysia Premier League. This however did not happen because of the cancellation of the 2020 season due to the COVID-19 pandemic, and was declared null and void. For the 2021 season, the AFL announced format changes in preparation for more participating teams to become professional by 2022. However, due to the pandemic, AFL postponed the start of the season to late 2021, before cancelling it altogether.
