The Transnational Government of Tamil Eelam (TGTE) is a government in exile among the Sri Lankan Tamil diaspora which aims to establish Tamil Eelam, a secular and democratic socialist state which the Liberation Tigers of Tamil Eelam aims to create in the north and east provinces of Sri Lanka since the early 1980s.

The TGTE has been called a "ploy to perpetuate terrorism" by the Government of Sri Lanka, which itself is under international pressure for alleged war crime probes, in addition to facing accusations, by rights activists, of orchestrating human rights violations, terrorism, organized crimes, crimes against humanity, ethnic cleansing and, above all, genocide. For its part, the TGTE has maintained that it is a democratic organization, and intends to use soft power and not military power to its end. The exact words found in TGTE constitution are : "Whereas the TGTE has guided us towards a democratic system of government, in order to establish an independent state of Tamil Eelam based on the principles of peace, non-violence, tolerance, pluralism, transparency and accountability".

Formed following the defeat of the Liberation Tigers of Tamil Eelam and the end of the Sri Lankan Civil War, the TGTE is based internationally, including in the United states of America, Canada, the United Kingdom, Australia, New Zealand, Norway, Germany, Italy, France and Switzerland. Its Prime Minister is Visvanathan Rudrakumaran, the former international legal advisor to the LTTE. Global elections were amongst Sri Lankan Tamil diaspora communities in May 2010 to elect members to the first Transnational Constituent Assembly of Tamil Eelam, the first step towards the formation of the PTGTE.
