The Nationwide Ceasefire Agreement (NCA), officially the Nationwide Ceasefire Agreement between the Government of the Republic of the Union of Myanmar and the Ethnic Armed Organisations (Burmese: တစ်နိုင်ငံလုံး ပစ်ခတ်တိုက်ခိုက်မှု ရပ်စဲရေးသဘောတူစာချုပ်), was a landmark ceasefire agreement between the government of Myanmar and representatives of various ethnic insurgent groups, officially known as "ethnic armed organisations" (EAOs) by the government.

The draft was agreed upon by a majority of the invited parties on 31 March 2015,[1] and the agreement was signed by President Thein Sein on 15 October 2015.

[7] The Lahu Democratic Union and the New Mon State Party later joined the ceasefire[8] and signed the agreement on 13 February 2018.

[9][10][11][12] Following the 1 February 2021 coup d'état, the Tatmadaw violated the ceasefire agreement by attacking the Restoration Council of Shan State's camps in Shanin Hsipaw Township.

[13] Since this violation, the majority of signatories to the agreement have left, including the ABSDF, CNF, KNU, PNLA, and (most recently) a splinter group of the New Mon State Party known as the NMSP (Anti-Military Dictatorship).
