Tharmapuram, or Dharmapuram, is a town in Kilinochchi District, Northern Province, Sri Lanka.
In 2008, the number of internally displaced persons (IDPs) in Kilinochchi District had been increasing.
Many IDPs were reported to have moved to Tharmapuram from Semmankunru and Kiranchchi areas.
By early October 2008, several institutions of the Liberation Tigers of Tamil Eelam were relocated to Tharmapuram from Kilinochichi.
Hence Tharmapuram had served shortly as the administrative center of the Liberation Tigers of Tamil Eelam.
