2021 Malaysia Super League

The 2021 Malaysia Super League (Liga Super Malaysia 2021), was the 18th season of the Malaysia Super League, the top-tier professional football league in Malaysia.

The defending champions from the 2020 Malaysia Super League season, Johor Darul Ta'zim, have managed to defend their title, securing their 8th consecutive title (since 2014) on 28 August 2021 although having 2 more matches left. On the other hand, Kedah who became the runner-ups have qualified to the 2022 AFC Cup. Penang who got third was a standby team for the AFC Cup and would qualify if the winners of the 2021 Malaysia Cup went to the Johor or Kedah, but they failed to and Kuala Lumpur City who became the champions ended up taking the spot.
