Qatar Stars League

The Qatar Stars League (Arabic: دوري نجوم قطر; abbreviated as QSL), known as Doha Bank Stars League for sponsorship reasons, is the top level football league in Qatar football league system. Contested by 12 teams, it operates on a system of promotion and relegation with the Qatari Second Division (QSD), with the lowest ranked club at the end of the QSL season being demoted to make room for the promotion of the highest ranked QSD club of the season. The QSL season usually runs from September to April. The league's first season was played in 1963, although the first official season occurred in 1972.

The Qatari league system provides 5 domestic cups that various clubs can compete for: the Emir of Qatar Cup, open to all teams in both the first and second divisions; the Qatar Crown Prince Cup, a postseason tournament played by the top four first division teams; the Sheikh Jassem Cup, a prelude to the first division regular season; the Qatari Stars Cup, a round-robin tournament played midseason; and the Qatar FA Cup, where the bottom 8 teams from the QSL and the entire QSD participate. The league title has been officially won by 7 clubs since its inception. The club that has won the most championships is Al Sadd SC, with 18 titles.

There are 2 divisions in the Qatari football structure and the league has previously seen one club promoted and relegated each year except in expansion seasons. The Qatar Stars League, previously known as the Q-League currently features 12 teams, with the 2nd division featuring 8 teams. The top four clubs at the end of the regular league system participate in the Qatar Crown Prince Cup, which was formed in the 1994/95 season.

The Qatar Stars League has slowly expanded since the turn of the decade, moving from 9 clubs to 10 clubs, and then latest setup of 12 clubs for the Qatari League 2009-10 campaign. It was announced that in the 2013-14 season, the number of clubs in the top division would increase to 14, whereas the second division would increase to 18 clubs which includes the reserve teams of the top division clubs.

It was announced on 15 April 2009 that no clubs would be relegated from the top flight in the 2008–09 Qatar Stars League season, due to expansion reasons, however the announcement was made with only one game remaining. That year, the top league expanded to 12 clubs. In May 2013, the QFA again expanded the league by two more teams, bringing the total number of clubs in the first division to 14. In 2017 the number of teams moved back to 12.

There are currently 4 official amateur football leagues in Qatar. Three amateur leagues are under the jurisdiction of the Qatar Community Football League (QCFL), established by the Supreme Committee for Delivery & Legacy, and the fourth, known as the Qatar Amateur League (QAL) is recognized by the QFA. Inaugurated in November 2013, the QAL has 14 teams, all of which were established through the country's government, political and social sectors.

The first unofficial season of the Qatar Stars League was the 1963–64 season, 3 years after the formation of the QFA. Similarly, a second division was also created during this time. For many years, there was no promotion or relegation system. Al-Maref, a club representing the Ministry of Education, was dissolved in 1966-67 by decision of the QFA and its players distributed to other clubs.

In 1972–73, the first official season was played. Al Esteqlal, now known as Qatar SC, won the first championship.
