Chin National Defence Force (Burmese: ချင်းအမျိုးသားကာကွယ်ရေးတပ်ဖွဲ့; abbreviated CNDF) is a Chin ethnic armed organisation in Myanmar.

It is the armed wing of the Chin National Organisation (CNO), and was founded on 13 April 2021 alongside it.

[3][4][5] It is one of the armed groups formed in Falam, Chin State of Myanmar in response to the Myanmar military's coup d'état after 1 February 2021.

[6][7] In 2024, the CNDF was one of the founding members of the Chin Brotherhood Alliance, siding with anti-junta groups who opposed the formation of Chinland by the Chin National Front (CNF).

The CNDF in Matupi Township warned the CNF to focus on taking the state capital Hakha, and that the group would fight back against further confrontations.
