The 2019–20 season was the 6th consecutive season of İstanbul Başakşehir in the Süper Lig and their 30th year in existence. The season was slated to cover a period from 1 July 2019 to 30 June 2020. It was extended extraordinarily beyond 30 June due to the COVID-19 pandemic in Turkey.
On 19 July 2020, Başakşehir were crowned champions of the Turkish Süper Lig for the first time in the club's history. They also became only the sixth club in the competition's history to win the league title.
