Charles Jayam Thambyrajah Thamotheram (19 September 1918 – 27 October 2005) was a Sri Lankan Tamil teacher, publisher and social worker.

[1][3][4] He then joined Ceylon University College, graduating with a second class honours degree in science.

[1][c] After a year, he returned to Wesley College but when the post of principal became vacant, Thamotheram should have been appointed but the discriminatory policies prevalent in Ceylon at that time meant he was ignored.

[3] He resigned from Wesley College in 1959 and joined the British Council in Colombo as a First Administrative Assistant.

[1][3] He also founded the Ceylon Teachers' Travel Club which organised tours to Australia, China, India, Israel, UK and USSR.

[1][2][3][4] Thamotheram and International Tamil Foundation opposed LTTE's proscription as a terrorist group in the United Kingdom.
