The NPC passed a resolution on Thursday demanding the revocation of the change in name of the island Nainathivu to the Sinhala name, Nagapattina.
The resolution, which was unanimously approved, said the government gazette mandating the change of the name was an attempt to distort history.
The chairman of the NPC, CVK Sivagnanam, who tabled the motion, stressed that the name must be changed back to its original name in Tamil.
Nainathivu is a heavily militarised islet off the coast of Jaffna in the Tamil-dominated North-East.
