The flag of the People's Republic of Kampuchea was a historical flag of Cambodia from 1979 to 1989, used during the Cambodian–Vietnamese War.
The flag that became the official flag of the People's Republic of Kampuchea had been previously adopted by the Kampuchean United Front for National Salvation (KUFNS), who had revived the flag of the Khmer Issarak in the days of anti-French resistance, declaring it the flag of the PRK.
