The Northeastern Line (Thai: ทางรถไฟสายตะวันออกเฉียงเหนือ) is a railway line in Thailand that connects the capital Bangkok with the northeast region of Isan. The section from Bangkok to Nakhon Ratchasima is Thailand's first line that opened for passenger service. The line is also a key section on the central route of the Kunming–Singapore railway.
