Football Division 3

Football Division 3 (ฟุตบอลดิวิชั่น 3) is the fourth level of Thai football organized by Football Association of Thailand.

In 2016, the tournament is divided into 5 regions and participated by 104 clubs which are former members Khǒr, Khor, and Ngor Royal Cup, and debutants in the season. As the tournament is considered as the lowest level of Thai football, so the number of participants is unlimited as well as any club is able to send an application to participate in the tournament.
