The Kingdom of Thekkumkur () (also transliterated as Thekkumkoor or Thekkumcore) was an independent kingdom in the southern part of Kerala in India from 1103 CE until 1750 CE. It was ruled by the Thekkumkur Royal Family (Edathil Family). Thekkumkur lies between the Meenachil River and the Pamba River, from the Western Ghats to the Vembanad Kayal. Thekkumkur emerges as a result of administrative changes in the princely states at the end of the Chera Kulasekhara dynasty of Mahodayapuram. The literal meaning of the title is the southern regent and the attribute southern distinguished them from another kingdom known as Vadakkumkur (northern regent) which bordered it in the northern side. The royal household, Thekkumkur Kovilakam, were at Vennimala and Manikandapuram near Puthuppally, later it shifted to Neerazhi Palace at Puzhavathu of Changanassery and Thalilkotta at Thaliyanthanapuram (Kottayam).
