Gosaba is a community development block that forms an administrative division in the Canning subdivision of the South 24 Parganas district in the Indian state of West Bengal.

Gosaba CD block is located at 22°09′55″N 88°48′28″E / 22.1652°N 88.8079°E / 22.1652; 88.8079. It has an average elevation of 6 metres (20 ft).

Gosaba CD block is bounded by Sandeshkhali II CD block in North 24 Parganas district in the north, Basanti CD block in the west and Sundarbans forests in the east and south. On the east, across the forests, there is the border with Satkhira District of Bangladesh. The Raimangal and Kalindi rivers run along the India-Bangladesh border.

South 24 Parganas district is divided into two distinct physiographic zones: the marine-riverine delta in the north and the marine delta zone in the south. As the sea receded southwards, in the sub-recent geological period, a large low-lying plain got exposed. Both tidal inflows and the rivers have been depositing sediments in this plain. The periodical collapse of both the natural levees and man-made embankments speed up the process of filling up of the depressions containing brackish water wetlands. The marine delta in the south is formed of interlacing tidal channels. As non-saline water for irrigation is scarce, agriculture is monsoon dominated. Some parts of the wetlands are still preserved for raising fish.

Gosaba CD block has an area of 296.73 km. It has 1 panchayat samity, 14 gram panchayats, 147 gram sansads (village councils), 51 mouzas and 50 inhabited villages, as per District Statistical Handbook for South Twenty-four Parganas. Gosaba and Sundarban Coastal police stations serve this CD Block. The headquarters of this CD block is at Gosaba.

Gosaba CD block has 372.5 km of embankments, the highest amongst the thirteen Sundarban CD Blocks. Breaches in these embankments varied from 6 km in 2003–04 to 54 km in 2006–07. Embankments raised along rivers are of critical importance for the safety of lives and protection of crops, against daily tides and tidal surges. Technologically the embankment structures are weak and there is need of proper drainage of accumulated rain water through sluice gates. Crude cuts in embankments for drainage of accumulated rain water and channels built for providing water to large fisheries (bheris) also add to the hazards. Cyclones and tropical depressions are regular threats.

Gram panchayats of Gosaba CD block/panchayat samiti are: Amtali, Bali-I, Bali-II, Bipradaspur, Chhota Mollakhali, Gosaba, Kachukhali, Kumirmari, Lahiripur, Pathankhali, Radhanagar Taranagar, Rangabelia, Satjelia and Shambhunagar.
