Karaitivu (Tamil: காரைதீவு, Sinhala: කාරතීවු) is a coastal village situated in the Eastern Coast of Sri Lanka about 30 miles (44 km) south of Batticaloa and is next to Kalmunai town.

[1] The village has 9–10 square meter area with 4 km long continuous sea boundary on the East and contains paddy lands on the West.

There are few smaller patches of coconut plantations and vegetable growing area in the south part of the village.

The continuing Sri Lankan civil war has adversely affected civilian population of this village resulting in many missing people, preponderance of widows and lack of development and employment opportunities.

Most farming and fishing related families lost all the required equipment to continue on with their professions.
