The Jathika Nidahas Peramuna (JNP) or National Freedom Front (NFF) is a political party in Sri Lanka which was formed by ten JVP parliamentarians led by Wimal Weerawansa, as a breakaway group of the Janatha Vimukthi Peramuna (JVP).

As the media reports, Weerawansa had an argument with the leadership based on the disarmament of the Tamil Makkal Viduthalai Pulikal (TMVP) political party, a breakaway faction of the LTTE which was contesting in the country's Eastern provincial council elections May 2008 under the banner of the ruling United People's Freedom Alliance (UPFA).

The dissident faction led by Wimal Weerawansa visited the most senior Buddhist monks of the Asgiriya and Malwatte chapters on 20 April 2008, to "obtain blessings for their new political movement".

[4] The party commenced political activities on 14 May 2008, the same day Rohana Wijeweera formed the JVP in 1965, and also the day of the infamous Anuradhapura massacre carried out by the LTTE, where 146 pilgrims at the Jaya Sri Maha Bodhi in Anuradhapura were brutally murdered by the LTTE.

[5] In October 2024, Wimal Weerawansa announced that the NFF would not be participating in the upcoming parliamentary elections, in hopes of increasing chances of the JVP-led National People's Power, led by President Anura Kumara Dissanayake, winning a majority in Parliament.
