2019–20 Irish Super League season

The 2019–20 Irish Super League season was the 47th running of Basketball Ireland's premier men's basketball competition. The season featured 12 teams from across the Republic of Ireland and Northern Ireland. The regular season began on 21 September 2019 and was scheduled to end on 14 March 2020. However, on 11 March 2020, Basketball Ireland suspended the league with one round to go due to the COVID-19 pandemic. As a result, Belfast Star were declared the season champions.

League
The 2019–20 season was cut short by one round due to the COVID-19 pandemic, with Tralee Warriors initially finishing on top of the standings with a 17–4 record. However, due to Tralee committing an unintentional rule violation by playing an illegal player in December 2019, they were stripped of two wins (six points) and thus Belfast Star were declared the season champions.

''*Later declared 0–20 losses for Tralee Warriors due to playing an illegal player. As a result, Tralee Warriors dropped from 17–4 to 15–6, while UCD Marian and Éanna both moved from 13–8 to 14–7.''
