The International Front of the Working People of the Latvian SSR or Interfront (Latvian: Latvijas PSR Internacionālā Darbaļaužu fronte, Interfronte, Russian: Интернациональный фронт трудящихся Латвийской ССР, Интерфронт, romanized: Internatsionalnyy front trudyashchikhsya Latviyskoy SSR; Interfront) was a pro-Soviet socialist organization in the Latvian SSR, which during the years 1989–1991, supported Latvia remaining part of the USSR.
In 1989 it took part in forming the United Front of Workers of the USSR (Объединенный фронт трудящихся СССР).
Interfront was particularly active during the January 1991 events in Latvia, during which several civilians and law enforcement officers were killed in clashes with OMON units loyal to the central government in Moscow.
In September 1991, following the failed August Coup attempt and the restoration of Latvian independence from the USSR, the transitional parliament, the Supreme Council passed a law banning Interfront and the Communist Party of Latvia.
Former Interfront activists who hold citizenship of Latvia have been prohibited from standing as candidates for election to the Saeima (parliament) or municipal councils.
