Vadamarachchi lagoon (Tamil : வடமராட்சி கடல்நீரேரி) is a lagoon in Jaffna District, northern Sri Lanka. The lagoon is sometimes referred to as Thondamannar lagoon. The lagoon separates the Vadamarachchi region from the Valikamam and Thenmarachchi regions.

The lagoon is connected to the Indian Ocean by a narrow channel to the north, near the town of Thondamannar. The lagoon's water is brackish to saline. There is a sluice gate at Thondamannar to prevent sea water entering the lagoon. [1]
