Narrabri is a locality and seat of Narrabri Shire local government area in the North West Slopes, New South Wales, Australia on the Namoi River, 521 kilometres northwest of Sydney. It sits on the junction of the Kamilaroi Highway and the Newell Highway. At the 2016 census, the town of Narrabri had a population of 5,903.
Because of the geography of Narrabri and the surrounding areas, Narrabri township was quite prone to flooding and fire. Recently, changes have been made to the river flow to improve overall safety.
It is the centre of a major cotton-growing industry. Other agricultural industries in the area include wheat, beef and lamb. Nearby attractions are Mount Kaputar National Park, the Australia Telescope Compact Array at the Paul Wild Observatory and a number of agricultural centres. Just to the south of town is the Pilliga Forest, the largest remnant temperate forest in Eastern Australia. Narrabri also has The Crossing Theatre, a 1,000-seat auditorium and cinema complex.
