The 2020 PBA season or PBA Season 45 was the 45th season of the Philippine Basketball Association. Due to the major adjustments in the last season's league calendar, the start of the league's 45th season was set on March 1, 2020, at the Smart Araneta Coliseum. However, the start of the 2020 season has been delayed until at least March 8 due to concerns over the COVID-19 pandemic. The PBA Leo Awards for the 2019 season were held before the opening ceremonies. The first official activity for this season was the 2019 PBA draft, held before the semifinals of the 2019 PBA Governors' Cup.
