The 2009 Intercity Football League season is the third since its establishment in 2007. It started from February 14, 2009.
At the end of 2008, the Chinese Taipei Football Association decided to merge the Enterprise Football League into the Intercity Football League, and therefore the latter became the highest-ranked football league in Taiwan.
The league included two divisions. Division A consisted of six teams, and the remaining teams participated in Division B. The last-placed team in Division A would be relegated to Division B while the champion of Division B would move up to Division A.
New league regulations required each team to be named after the administrative division in which they were located. Each team also needed two-thirds of its players to reside in the area for at least one month.
Taipei City Tatung, Tainan County, and Kaohsiung Taipower automatically qualified for Division A after finishing in the top four places in the 2008 season. The remaining three Division A places were decided via a qualification tournament, which took place at the Pailing Sport Park January 1–4, 2009. There were six teams competing in the tournament: Miaoli County, Kaohsiung City, Kaohsiung City Yoedy (高市耀迪),[1] Yilan County, Taipei County Hanchuang (北縣悍創), and Tainan City. Taipei County Hanchuang, Kaohsiung City Yaoti, and Kaohsiung City qualified for Division A after finishing in the top 3 places in the qualification tournament.
Taipei County Sanchung football team consists of students and graduates of National San Chung Senior High School. Most of them are still high-school students, therefore they have the lowest average age among all participating teams.
