2011 Thai Division 1 League
2011 Thai League Division 1 is the 14th season of the League since its establishment in 1997. It is the feeder league for the Thai Premier League. A total of 18 teams will compete in the league.
League expansion
It was announced at the end of the 2010 season that the TPL would increase the number of teams for the start of the 2011 Thai Premier League season. Therefore, playoff games were arranged to promote more teams for the Regional League Division 2 and relegate less teams from the TPL. During these games, Nakhon Pathom were banned and therefore will fail to take their place in Division 1 for the next two seasons. This did mean that the league would only feature 17 teams for the season, but with less than 3 weeks before the start of the league campaign another round of playoffs was used to promote one more side, Saraburi.Changes from last season
