2020–21 Saudi Pro League

The 2020–21 Saudi Professional League was the 45th edition of the Saudi Professional League, the top Saudi professional league for association football clubs, since its establishment in 1976. The season began on 17 October 2020 as a consequence of the postponement of the previous season's conclusion due to the COVID-19 pandemic. Fixtures for the 2020–21 season were announced on 29 September 2020.

Al-Hilal are the defending champions after winning the Pro League for the 16th time last season. Al-Ain, Al-Batin, and Al-Qadsiah join as the three promoted clubs from the 2019–20 MS League. They replace Al-Adalah, Al-Fayha, and Al-Hazem who were relegated to the 2020–21 MS League.

On 29 March, the Ministry of Sports announced that fans will be allowed to return to stadiums for the final three rounds of matches with a maximum of 40% capacity.

On 23 May, Al-Hilal secured their seventeenth league title with one match to spare following a 1–0 away win against Al-Taawoun. It was also the club's second consecutive title and fourth in the last five seasons. Al-Ain were the first team to be relegated following a 2–0 defeat away to Al-Nassr on 14 May. In the final matchday, both Al-Qadsiah and Al-Wehda were relegated following a draw with Abha and a loss against Al-Shabab respectively.

Positions by round
The following table lists the positions of teams after each week of matches. In order to preserve the chronological evolution, any postponed matches are not included to the round at which they were originally scheduled but added to the full round they were played immediately afterward. If a club from the Saudi Professional League wins the King Cup, they will qualify for the AFC Champions League, unless they have already qualified for it through their league position. In this case, an additional AFC Champions League group stage berth will be given to the 3rd placed team, and the AFC Champions League play-off round spot will be given to 4th.
