Perang Kamboja–Vietnam (bahasa Vietnam:Chiến dịch phản công biên giới Tây-Nam Việt Namcode: vi is deprecated , bahasa Khmer:យុទ្ធនាការប្រឆាំងនៅព្រំដែនភាគនិរតីវៀតណាមcode: km is deprecated ) adalah konflik yang terjadi antara Republik Sosialis Vietnam dan Kamboja Demokratik. Perang ini dimulai dengan invasi dan pendudukan Vietnam terhadap Kamboja, pelengseran rezim Khmer Merah dari kekuasaan dan berakhirnya genosida Kamboja.
Perang ini dimulai dengan kekhawatiran Demokratik Kampuchea yang pada saat itu di bawah pimpinan Pol Pot akan meluasnya pengaruh Vietnam setelah kemenangan Vietnam pada Perang Vietnam. Kekhawatiran ini didasarkan atas keinginan Vietnam untuk menyatukan kawasan Indochina dalam suatu negara di bawah kekuasaan Vietnam. Dibawah kekhawatiran tersebut, Demokratik Kampuchea melancarkan aksi untuk menetralisir tentara Vietnam di sekitar perbatasan Vietnam-Kamboja. Atas aksinya, Vietnam membalas dengan melancarkan invasi melawan Demokratik Kampuchea yang menyebabkan keruntuhan Demokratik Kampuchea yang kemudian diganti oleh negara boneka Vietnam, Republik Rakyat Kamboja. Pendudukan Vietnam berakhir setelah tekanan internasional serta reformasi politik Vietnam. Tentara Vietnam terakhir keluar Kamboja pada tahun 1992.
12Vietnamese sources generally offer contradictory figures, but Vietnamese General Tran Cong Man stated that at "least 15,000 soldiers died and another 30,000 were wounded in the ten-year long Cambodian campaign"—so the figures do not include the casualties from the period between 1975 and 1979.

↑By 1989, the Khmer Rouge maintained the largest fighting force amongst the three factions which made up the Coalition Government of Democratic Kampuchea. The KPNLF had less than 10,000 men, and FUNCINPEC had 2,000 fighters.
↑From an invasion force of 150,000, Vietnamese troop strength was estimated to have peaked at around 200,000 until Vietnam began their unilateral withdrawal in 1982.[4]
