The Cambodian–Vietnamese War was an armed conflict that lasted from 1978 to 1989.

It involved the Khmer Rouge and Vietnam, along with their various allies. This struggle was a part of the Third Indochina War. It also occurred during the Cold War, a time of global tension. The Soviet Union supported Vietnam during this period. Meanwhile, China provided support to the Khmer Rouge. Although both sides were communist, their alliance collapsed after they both gained power in their own countries.

The conflict grew from deep political fears and historical disagreements. The Khmer Rouge was led by Pol Pot. His leadership group feared that Vietnam intended to create an Indochinese federation. They believed Vietnam would dominate the entire region. The Khmer Rouge also held irredentist sentiments regarding the Mekong Delta. This means they wanted to reclaim territory they believed belonged to Cambodia. Because of these tensions, the Khmer Rouge launched military attacks against Vietnam. In April 1978, the Khmer Rouge committed the Ba Chúc massacre. During this event, over 3,000 Vietnamese civilians were killed.

Vietnam responded to these attacks with military action. On December 21, 1978, Vietnam launched a limited offensive toward Kratie. On December 23, the Khmer Rouge's Kampuchea Revolutionary Army opened fire along the border. They targeted the southwestern provinces of Đồng Tháp, An Giang, and Kiên Giang. Vietnam then launched a full-scale invasion on December 25, 1978. They supported Cambodian dissidents who were in exile. The Vietnamese army occupied the country in just two weeks. They captured the capital city, Phnom Penh, and removed the Khmer Rouge from power.

This invasion had a massive impact on the Cambodian people. It brought an end to the Cambodian genocide. This genocide had killed between 1.2 and 2.8 million people. That number represented between 13 and 30 percent of the total population.

The Vietnamese occupation also helped facilitate international food aid. This aid was necessary to mitigate a massive famine. However, the occupation was not without tension. Many Cambodians felt discontent regarding the presence of Vietnamese forces. The Khmer Rouge regime also kept its seat at the United Nations. This led to Vietnam being isolated from most of the international community.

After the fall of Phnom Penh, a new government was established. This was the People's Republic of Kampuchea, or the PRK.

The Khmer Rouge did not stop fighting. They retreated into the jungles near the Thai border. They joined other groups to fight the Vietnamese and the pro-Vietnamese government. These included the Khmer People's National Liberation Front and FUNCINPEC. FUNCINPEC was led by the former king, Norodom Sihanouk. In 1982, these groups formed the Coalition Government of Democratic Kampuchea.

They received training in Thailand from the British Army's Special Air Service.

Vietnam eventually faced domestic difficulties that forced a change in policy. They began to implement economic and foreign policy reforms. Under pressure from the international community, Vietnam gradually withdrew its troops. The Vietnamese army completely left Cambodia in September 1989.

In 1990, representatives met at the Third Jakarta Informal Meeting. They worked under the Australian-sponsored Cambodian Peace Plan. This led to the creation of the Supreme National Council. This council represented Cambodian sovereignty on the international stage.

The final steps toward peace were managed by the United Nations. The United Nations Transitional Authority in Cambodia supervised domestic policies. In May 1993, general elections were held. The FUNCINPEC movement won the election, defeating the Cambodian People's Party. To ensure stability, FUNCINPEC leader Norodom Ranariddh formed a coalition government. This process restored the constitutional monarchy in the Kingdom of Cambodia.
