"Dap Prampi Mesa Moha Chokchey" (Khmer: ដប់ប្រាំពីរមេសាមហាជោគជ័យ, UNGEGN: Dap Prampi Mesa Moha Chouk Chey) was the national anthem of Democratic Kampuchea from at least January 1976.

Supposedly, the Khmer Rouge and/or Pol Pot himself wrote the piece, but its origin remains unknown.

[1] After Vietnam militarily intervened and forced the Khmer Rouge out of most of Cambodia, the People's Republic of Kampuchea was established and used a new anthem.

However, the Coalition Government of Democratic Kampuchea continued to use "Dap Prampi Mesa Moha Chokchey" as its state anthem in exile.
