Nijhum Dwip (Char Osmani, Baluar Char, Golden Island ) is a small island under Hatiya upazila of Noakhali. A cluster of islands (mainly, Ballar Char, Kamlar Char, Char Osman and Char Muri) emerged in the early 1950s as alluvium in the shallow estuary of the Bay of Bengal on the south of Noakhali. These new sandbanks first drew the attention of a group of fishermen, who named it Baular Char. In 1974 the Forest Department began an aforestation program for twenty years on the north side of the island. Covering an area of , it has now developed into a deep forest with a variety of plant species. Among the trees Keora is often seen. Besides this Gewa, Kankra, Bain, Babul, Karamja, Pashur and many other species are in evidence. It was renamed 'Nijhum Dweep' by former Minister Amirul Islam Kalam in 1979 after observing its isolation and mild nature.
