The Hungarian invasion of Carpatho-Ukraine was a 1939 military conflict between the Kingdom of Hungary and Carpatho-Ukraine. During the invasion a series of clashes took place between the Hungarian and Polish troops against the paramilitary formations of the Carpathian Sich of Carpathian Ukraine and some Czech troops who remained in the region after the Czechoslovak army was disbanded. The war ended with the occupation and subsequent annexation of the territory of Transcarpathian Ukraine (Subcarpathian Rus') to the Kingdom of Hungary.

This territory was later invaded by the Soviet Union and integrated into its Ukrainian SSR.
