Cox's Bazar Beach, Continuous sandy beach in Cox's Bazar District, Bangladesh

Cox's Bazar Beach is a continuous sandy stretch along Bangladesh's southeastern coast in Cox's Bazar District, running roughly 120 km in length. The golden-brown sand extends without breaks from Cox's Bazar town southward to Teknaf, forming the longest natural beachfront in the country.

Captain Hiram Cox, a British East India Company officer, was appointed superintendent of Palonki after Warren Hastings became Governor of Bengal in 1773. Cox worked to resettle Arakanese refugees but died in 1799 before finishing; a market named Cox's Bazar was founded in his memory. The thana was established in 1854 and the municipality in 1869.

Families gather here during holidays and weekends, walking along the shore while vendors sell coconut water and local snacks from makeshift stalls. Fishermen set out before dawn and return with their catch, which is sold fresh at the nearby markets throughout the day.

The beach is widest at low tide, when the sand extends about 400 metres from the waterline, and narrows to roughly 200 metres at high tide. Quicksand can form during ebb tide, so avoid walking on freshly exposed wet sand. Laboni Point is the main gathering spot for horseback and speed-boat rides, while buses now stop near Dolphine Moor rather than on the beach itself.

Tidal shifts create changing zones along the waterline each day, where visitors can spot different shell species and small marine creatures when the water recedes. Temporary sandbars emerge in certain sections after the tide pulls back, attracting gulls and other coastal birds that gather to feed.
