The Mungindi railway line is a railway line in northern New South Wales, Australia. It branches from the Main North line at Werris Creek station and heads north-west through the towns of Gunnedah and Narrabri before reaching Moree which for many years was the railhead before the extension to Mungindi was constructed. The line is currently truncated to Weemelah between Moree and Mungindi. Passenger trains still operate to Moree, and goods trains operate to Camurra. As of 1 September 2009, services have been suspended between Camurra and Weemelah. The line between Werris Creek and Moree is also known as the North-West line.

As of 1988, the line closed progressively north of Armidale with services gradually withdrawn till 2004, with the main route between Sydney and Brisbane now the North Coast line.
