Thanon Chira Junction railway station (SRT Code: TNJ) (Thai: สถานีรถไฟชุมทางถนนจิระ (จร.))

is the main railway station in Nakhon Ratchasima Province, Thailand.

In the 2008 census, Thanon Chira Junction railway station served nearly 350,000 passengers.

The station became a junction in 1934 once the line to Khon Kaen was completed,[1] and opened on 1 April 1933.

The location of the station is important because it is close to both Nakhon Ratchasima and the gate of Fort Suranaree (the headquarters of 2nd Army Region).
