The 2019–20 Persian Gulf Pro League was the 37th season of Iran's Football League and 19th as Persian Gulf Pro League since its establishment in 2001. Persepolis are the defending champions and won their record-extending 4th consecutive title and 13th title overall on 24 July with four games to spare. The season featured 14 teams from the 2018–19 Persian Gulf Pro League and two new teams promoted from the 2018–19 Azadegan League: Shahin Bushehr and Gol Gohar Sirjan.

The Persian Gulf Pro League, formerly known as the Iran Premier League, is the highest division of professional football in Iran. Each year, its top team becomes the Iranian football champion, and the two lowest finishers are relegated to Azadegan League.
