Vaddukoddai (Tamil: வட்டுக்கோட்டை, romanized: Vaṭṭukkōṭṭai, Sinhala: වඩුකෝඩයි) (also spelt Vatukotai, Vaddukkoddai) is small but important town in the minority Sri Lankan Tamil dominated Jaffna peninsula of Sri Lanka.

It became prominent with the founding of Asia’s first modern university level collegiate known as Batticotta Seminary by the American Missionaries from New England in 1823.

As of 2007, due to the effects of the Sri Lankan civil war the actual number of residents is unknown.

[2] The name of the village suggests that at some point in its history it had a fortress in its midst, possibly from the Aryacakravarti dynasty.

The village became prominent during the British colonial period in Sri Lanka as it was chosen as location for one of the nine protestant missions to be established within the small Jaffna peninsula (hardly 15 by 40 miles).
