The Qatari Second Division (Arabic: دوري الدرجة الثانية القطري), QSD or Second Division League, also was known as Qatargas League due to sponsorship reasons, is the second tier of the two-tier football league competition in Qatar. Contested by 8 teams, it operates on a system of promotion and relegation with the Qatar Stars League (QSL), the top-tier football league in the country. The QSD seasons, like those of the QSL, run from September to April.
The league's first season was played in 1979 which was won by Al-Ittihad. The club with the most QSD wins is Al-Markhiya which has won 6 QSD titles. According to the league's development strategy, starting with the 2022–23 season, the first-placed club of this league will play a relegation match against the tenth-placed club of the first league to decide which club will participate in the first league next season. There is no relegation from the second division.
