Kokkilai lagoon is an estuarine lagoon in Mullaitivu District and Trincomalee District, north-east Sri Lanka. The town of Kokkilai is located on a sand bar between the lagoon and the Indian Ocean. The lagoon is fed by a number of small rivers, including Churiyan Aru. It is linked to the sea by a narrow channel that is very often blocked by the sand bar. The lagoon's water is brackish. The lagoon is surrounded by a densely populated region containing cultivated land, scrubland and open forest. The land is used for prawn fishing, paddy cultivation and some shifting cultivation. The lagoon has extensive sea grass beds.
