Narrabri is a town and seat of Narrabri Shire Council local government area in the North West Slopes, New South Wales, Australia on the Namoi River, northwest of Sydney. It sits on the junction of the Kamilaroi Highway and the Newell Highway. At the 2011 census, Narrabri had a population of 5,890.
As a result of the geography of Narrabri and the surrounding areas, Narrabri township is quite prone to flooding.
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 (administered by the CSIRO) and a number of agricultural centres, including the Australian Cotton Exhibition Centre. 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.
