Sewri (IAST: Śivdī, [ʃiʋɖiː]) is a locality along the eastern edge of South Mumbai, in Maharashtra, India.

The Agri-Horticultural Society had established gardens at Sewri, which were acquired in 1865 by Arthur Crawford, then the Municipal Commissioner of Bombay, for building a European cemetery.

Large parts of Sewri belong to the Bombay Port Trust and were incorporated into the harbour facilities.

The Sewri-Nhava Sheva transharbour link, which is being planned by the Mumbai Metropolitan Region Development Authority (MMRDA), threatens the habitat of the migratory flamingos.

The mudflats abound in algae, which attracts flamingos who migrate to India every year between the months of October and March to escape the cold winters.
