Sundarbans South Wildlife Sanctuary, Protected mangrove forest in Khulna Division, Bangladesh.

Sundarbans South Wildlife Sanctuary is a dense mangrove forest covering roughly 37,000 hectares, intersected by tidal waterways and small islands along the Bay of Bengal. The landscape features intricate water channels that connect wildlife and vegetation throughout the protected area.

The sources record no founding date or colonial management history for this reserve. It is one of three wildlife sanctuaries into which the Bangladesh Sundarbans is divided, alongside the East and West sanctuaries, and it borders the Sundarbans National Park of West Bengal, India. Bangladesh's Forest Department lists it among the country's wildlife sanctuaries.

The sanctuary is one of three Sundarbans wildlife sanctuaries, alongside the Sundarbans East and Sundarbans West sanctuaries, and it lies beside the Sundarbans National Park of West Bengal, India. Under Bangladesh's vulture safe zone schedule 2, it is declared a safe area for vultures.

Visitors require permits from Bangladesh Forest Department authorities to enter the area, and guided tours operate mainly during the dry season from November to February. The best time to visit is when weather conditions are more stable and waterways are easier to navigate.

Gewa (Euphorbiaceae) is the sanctuary's dominant woody species, with Sundri (Heritiera fomes) abundant alongside it. Where Sundri regenerates poorly, a dense understory is created artificially to help it grow. The sanctuary is also declared a vulture-safe area under Bangladesh's Vulture Safe Area-2 schedule.
