The 2019–20 Swiss Basketball League (SBL) season was the 89th season of the top tier basketball league in Switzerland.
On 13 March 2020, the season was ended prematurely due to the COVID-19 pandemic[1] and no champion was declared.
The six first qualified teams would join the group for places 1 to 6 while the other six teams would play the group for places 7 to 12.
These two groups would be played with a one-legged round-robin format, where all teams from group 1 to 6 and the two first qualified teams from the group for the seventh position would be qualified for the playoffs.
[2] However, due to the COVID-19 pandemic, the league ended with two rounds of the regular season without being played.
