Roi-Et PB United

The club was established in 2008 and joined Regional League Division 2 North Eastern Region. They finished bottom of the division in 2009, but were champions of the division two seasons later, advancing to the promotion play-offs, in which they finished fourth in a six-club group. They won their division again in 2012, but again only finished fourth in the promotion play-off group stage. After winning their regional division for a third successive season in 2013, the club won their group in the promotion play-offs, before going on to win the knock-out stages, defeating Chiangmai 2–0 on aggregate over two legs and earning promotion to Division One.

Roi Et's first season in Division One saw them finish fourth-from bottom, two points from safety, resulting in relegation straight back to Division Two. Following league reorganisation in 2017, the division was renamed League 4. The club were excluded from the league the following year after failing to obtain a licence from the Thai FA. However, they were subsequently rebranded as Roi Et CF and allowed to enter the North Eastern Region of the Thailand Amateur League for the 2018 season.
