The Pamban Bridge is a railway bridge that connects the town of Mandapam in mainland India with Pamban Island, and Rameswaram. Opened on 24 February 1914, it was India's first and the longest sea bridge (2.06 km, 1.28 miles) until the opening of the Bandra-Worli Sea Link (5.60 km, 3.48 miles) in 2010.

The rail bridge is a conventional bridge resting on concrete piers, but has a double-leaf bascule section midway, which can be raised to let ships and barges pass through. Until 1988, the Pamban bridge was the only surface transport link that connected Tamil Nadu's island of Rameswaram to the mainland. Subsequently a road bridge was built in 1988.

In December 2018, the bascule of this bridge was damaged, which suspended rail traffic on the bridge for 3 months. Rail movement was again restored in February 2019.
