Chundikkulam Lagoon (Tamil: சுண்டிக்குளம் கடல் நீரேரி, Sinhala: කුම්බවැව Kumbavæwa) is a lagoon in Jaffna District and Kilinochchi District, north-east Sri Lanka. The town of Chundikkulam is located on a narrow piece of land between the lagoon and the Indian Ocean. The lagoon is sometimes referred to as Elephant Pass Lagoon. The lagoon is surrounded by palmyra palm plantations and scrubland. The land is used for prawn fishing and some salt production. Most of the lagoon was designated a bird sanctuary in 1938.
